Plantar Fasciitis Treatment That Targets
Your Heel, Not Your Whole Body
Medically Reviewed By: Jennifer Brown, MD · Board-Certified Family Medicine
Yes, topical pain relief works for plantar fasciitis. The plantar fascia sits within millimeters of the skin on the sole of the foot, one of the most accessible structures for topical drug delivery. Topical NSAIDs put the medication on the skin over the painful area, with lower systemic exposure than the same drug taken by mouth. Lower, not zero.
Plantar fasciitis is inflammation of the plantar fascia, the thick band of connective tissue running from the heel bone to the base of the toes. It's the most common cause of heel pain, affecting roughly 1 in 10 people over their lifetime. That stabbing pain with your first steps in the morning? That's inflamed fascia tearing with every step.
The plantar fascia is superficial, it sits just under the skin on the sole of the foot. That makes your heel one of the most accessible locations on the body for topical anti-inflammatory delivery. Medication absorbs right where the inflammation is, without passing through your stomach first.

Plantar Fasciitis Treatment: Key Takeaways
- The plantar fascia sits within millimeters of the skin on the sole of the foot, making the heel one of the most accessible locations on the body for topical anti-inflammatory delivery.
- In a Cochrane review subgroup of two studies (314 participants) testing diclofenac Emulgel for acute musculoskeletal pain, the number needed to treat was 1.8. Across all topical diclofenac formulations in that review it was 3.7. These are diclofenac figures, not ketorolac.
- In a national US survey, 49.47% of adults reporting diagnosed plantar fasciitis with recent pain used over-the-counter NSAIDs, and 4.01% used prescription NSAIDs for it. Topical diclofenac 1% gel produced 5-17x lower systemic exposure than oral diclofenac in healthy volunteers.
- Cortisone injections for plantar fasciitis carry risks of fat pad atrophy and plantar fascia rupture. Topical NSAIDs deliver anti-inflammatory medication to the fascia without these structural risks.
For Plantar Fasciitis Pain & Flares

Plantar fasciitis is inflammation of the plantar fascia, the thick band of tissue that connects the heel bone (calcaneus) to the toes. It is the most common cause of inferior heel pain, affecting approximately 10% of the population over a lifetime. Pain is typically worst with the first steps of the day.
Quick Facts
- Affects ~10% of people over their lifetime, peak incidence ages 40-60
- Plantar fascia sits within millimeters of skin, ideal for topical delivery
- 49.47% of surveyed US adults with plantar fasciitis pain used OTC NSAIDs (Nahin 2018)
- Cochrane NNT of 1.8 is a diclofenac Emulgel subgroup in acute MSK pain, not plantar fasciitis
- ACR strongly recommends topical NSAIDs for knee OA, conditionally for hand OA
Why Your Heel Won't Stop Hurting
The plantar fascia is a thick, fibrous band running from your heel bone to the base of your toes. It acts as a shock absorber and supports the arch of your foot with every single step. It absorbs 2-3x your body weight each time your foot hits the ground. Over thousands of steps per day, that's an enormous amount of repetitive stress on one structure.
Plantar fasciitis starts when the fascia sustains micro-tears faster than your body can repair them, usually at the attachment point on the calcaneus (heel bone). The tissue becomes inflamed, thickened, and painful. That classic stabbing pain with your first morning steps? It's the inflamed fascia re-tearing after tightening overnight. The pain often improves with movement as the tissue warms up, then returns after prolonged standing or sitting.
49.47%
Of US adults reporting diagnosed plantar fasciitis with pain in the past month, 49.47% reported using over-the-counter NSAIDs and 4.01% reported prescription NSAIDs for it, in an analysis of the 2013 National Health and Wellness Survey. Most of that use is oral, which means the medication is distributed through the whole body rather than applied where the pain is.
The critical advantage for topical treatment: the plantar fascia is superficial. It sits within millimeters of the skin on the sole of the foot. Unlike deep joints or internal organs, the inflamed tissue is right there, directly accessible through the skin. That's what makes topical anti-inflammatory treatment applied directly to the heel a logical approach for this specific condition.
"I've been dealing with plantar fasciitis for over a year. Ibuprofen was tearing up my stomach and the cortisone shot only lasted a month. The prescription gel goes right on my heel, felt the difference within a week."

What People Try for Plantar Fasciitis, And Why It Falls Short
Plantar fasciitis treatment is a cycle of frustration. Stretching, insoles, pills, injections, rest, repeat. Most options either mask symptoms temporarily or ignore the inflammation driving the pain.
Oral NSAIDs (Ibuprofen, Naproxen)
A systemic drug for one structure on the bottom of your foot. Your entire GI tract, kidneys, and liver process the medication when you only need anti-inflammatory action at the plantar fascia. In a national US survey, 49.47% of adults with plantar fasciitis pain reported using OTC NSAIDs, most of them oral.
Systemic drug for a localized problem
Cortisone Injections
Provide temporary relief but carry specific risks for plantar fasciitis: fat pad atrophy (thinning the protective cushion under the heel) and plantar fascia rupture. These are not minor risks for a weight-bearing structure you use with every step. Relief typically lasts 4-8 weeks.
Fat pad atrophy risk, fascia rupture risk
Night Splints
Hold the foot in dorsiflexion overnight to prevent the fascia from tightening. The theory is sound but compliance is terrible, most people can't sleep with a rigid splint on their foot. They address morning stiffness but don't reduce inflammation.
Low compliance, doesn't treat inflammation
Orthotics / Insoles
Redistribute pressure and support the arch. Can reduce mechanical load on the fascia, which helps with symptom management. But orthotics don't address the underlying inflammation, they change how force is distributed, not whether the tissue is inflamed.
Mechanical support, doesn't address inflammation
"Every morning I dread those first steps out of bed. It's like stepping on a nail. I've tried the insoles, the stretches, the night splint I couldn't sleep in. The cortisone shot helped for a month then the pain came back. My doctor says there's not much else to do besides wait."

Topical vs. Oral: Why Delivery Method Matters for Plantar Fasciitis
The plantar fascia sits close to the surface, on the sole of the foot. A topical NSAID is applied to the skin over the painful area rather than taken by mouth. The ACR strongly recommends topical NSAIDs for knee osteoarthritis and conditionally recommends them for hand osteoarthritis, which is osteoarthritis guidance and does not cover plantar fasciitis. Topical diclofenac 1% gel produced 5-17x lower systemic exposure than oral diclofenac in healthy volunteers (Kienzler 2010).
Topical Delivery
Medication is applied to the skin over the painful area of the heel rather than swallowed.
- Plantar fascia is superficial, within millimeters of skin
- 5-17x lower systemic exposure for diclofenac 1% gel vs oral diclofenac
- Lower systemic exposure than oral NSAIDs. Lower, not zero.
- Lower systemic exposure than the same drug taken by mouth
- Self-applied daily, no office visits or injections
Oral Systemic
Pill dissolves in stomach, enters bloodstream, distributes everywhere. Only a fraction reaches the fascia you're trying to treat.
- Treats entire body for one structure on the foot
- Full systemic drug exposure
- GI bleeding risk increases with duration
- Kidney function declines over years
- Cardiovascular risk with long-term use
Does Voltaren Gel Work For Plantar Fasciitis?
Voltaren Arthritis Pain is diclofenac 1%, and the foot is one of the six body areas its over-the-counter label permits. But the labeled use is arthritis pain, and plantar fasciitis is not arthritis. The label does not name the condition in either direction, so a licensed provider is the right person to answer whether it fits your case.
The Drug Facts label is specific about where the product goes, what it treats, how often to apply it and how long to keep going. Most of that is printed on the carton, and most people never read it.
What The OTC Label Actually Covers
Voltaren Arthritis Pain lists six permitted body areas: hand, wrist and elbow on the upper body, foot, ankle and knee on the lower body. The foot is on that list. The Uses section reads "for the temporary relief of arthritis pain ONLY in the following areas," so the indication is arthritis pain. The label does not name plantar fasciitis in either direction. It does carry a Do Not Use line for strains, sprains, bruises or sports injuries, stating the product has not been shown to work for those types of injuries. Plantar fasciitis is not on that list either.
The Name Says Inflammation. The Tissue Often Disagrees.
American Family Physician states that plantar fasciopathy is an appropriate descriptor because the condition is not inflammatory. That reading comes from histology: in 50 specimens taken during heel spur surgery for chronic plantar fasciitis, the finding was myxoid degeneration with fragmentation and degeneration of the plantar fascia rather than an inflammatory picture. It does not make an anti-inflammatory pointless. The same AFP review says treatment should start with stretching of the plantar fascia, ice massage, and nonsteroidal anti-inflammatory drugs. That sentence does not specify a route, so it is not a statement about creams in particular. What it does mean is that an NSAID is one part of a plan that also has to deal with load, footwear and calf tightness.

What The Topical NSAID Evidence Covers
In a Cochrane review subgroup of two studies (314 participants) testing diclofenac Emulgel for acute musculoskeletal pain, the number needed to treat for at least 50% pain reduction was 1.8. Across all topical diclofenac formulations in that review it was 3.7. These are diclofenac figures, not ketorolac. The conditions the review covers are sprains, strains and overuse injuries, and its authors concluded that topical NSAIDs provided good levels of pain relief in those conditions. The review does not cover plantar fasciitis, so a licensed provider is the right person to say how much of it applies to your heel.
How The Label Says To Use It
For the areas it covers, the label directs four applications per day, on no more than two body areas at the same time, for up to 21 days unless a doctor says otherwise. It also says the product may take up to seven days to work for arthritis pain and is not for immediate relief. That is the label's arthritis figure. The label sets out no response timeline for plantar fasciitis. Apply only to clean, dry skin with no cuts, open wounds, infections or rashes. Do not use external heat such as a heating pad over the area, do not bandage it, and ask a doctor or pharmacist before use if you take other drugs.
49.47%
Share of US adults reporting diagnosed plantar fasciitis with pain in the past month who reported using over-the-counter NSAIDs, in an analysis of the 2013 National Health and Wellness Survey. Prescription NSAIDs used specifically for plantar fasciitis pain were reported by 4.01% (Nahin, J Pain 2018).
A licensed provider can advise where each option fits, confirm the diagnosis, and look at load and footwear alongside anything applied to the skin. Ketro's RX Pain Gel consultation is one route to that review. There is no head-to-head data comparing prescription topical ketorolac with OTC diclofenac for plantar fasciitis.
Prescription Heel Cream + Daily Comfort
Prescription-strength anti-inflammatory for plantar fasciitis flares. Daily magnesium as a comfort product for general foot tension. The topical NSAID is the evidence-based treatment for plantar fasciitis.

What The Research Says About Topical NSAIDs And Heel Pain
Real studies, real data. Not marketing claims, peer-reviewed evidence supporting topical delivery for plantar fasciitis and musculoskeletal pain.
Topical NSAIDs In Acute Musculoskeletal Pain
A Cochrane review of topical NSAIDs in acute musculoskeletal pain reported that topical NSAIDs provided good levels of pain relief in acute conditions such as sprains, strains and overuse injuries, probably similar to that provided by oral NSAIDs. That review covers acute soft tissue conditions. It does not cover plantar fasciitis, so it supports the delivery route rather than a plantar fasciitis result.
Cochrane NNT Figures For Topical Diclofenac
In a Cochrane review subgroup of two studies (314 participants) testing diclofenac Emulgel for acute musculoskeletal pain, the number needed to treat for at least 50% pain reduction was 1.8. Across all topical diclofenac formulations in that review it was 3.7. These are diclofenac figures, not ketorolac, and the review covers acute musculoskeletal pain rather than plantar fasciitis.
ACR Guidance On Topical NSAIDs In Osteoarthritis
The American College of Rheumatology strongly recommends topical NSAIDs for knee osteoarthritis and conditionally recommends them for hand osteoarthritis. Topical capsaicin is also conditionally recommended for knee OA. That guidance covers osteoarthritis of the hand, hip and knee. It is not a recommendation for plantar fasciitis. Topical diclofenac 1% gel produced 5-17x lower systemic exposure than oral diclofenac in healthy volunteers.

Plantar Fasciitis Cream And Voltaren FAQ
Plantar fasciitis is not arthritis, and the label does not name it in either direction. That makes heel use for plantar fasciitis a question for a pharmacist or clinician rather than something the carton answers. The label also says to apply only to clean, dry skin with no cuts, open wounds, infections or rashes, and not to cover the area with a bandage or a heating pad.
For the condition itself, American Family Physician reports that with proper treatment, 80% of patients with plantar fasciitis improve within 12 months. So no plantar-fasciitis-specific onset figure is established for this product, and a licensed provider is the right person to set expectations for your case.
Two caveats matter more than brand choice. The diclofenac label indicates the product for arthritis pain, not for plantar fasciitis. And the headline evidence figure people quote, a number needed to treat of 1.8, comes from a Cochrane review subgroup of two studies with 314 participants testing diclofenac Emulgel in acute musculoskeletal pain; across all topical diclofenac formulations in that review it was 3.7. Those are diclofenac figures, not ketorolac, and the review does not cover plantar fasciitis. A licensed provider can advise where each option fits.
Read the Drug Facts panel on the specific carton you buy rather than assuming two products carry identical directions. Prescription topical NSAIDs are a separate matter: they are dispensed under a clinician's direction, which is also where use outside a product's labeled indication gets assessed properly. Voltaren compared with Ketro RX Pain Gel sets out how OTC diclofenac and prescription topical ketorolac differ.
The same AFP review still says treatment should start with stretching of the plantar fascia, ice massage, and nonsteroidal anti-inflammatory drugs. That sentence does not specify a route, so it is not a statement about creams in particular. An NSAID has a role in pain control, but it is not the whole plan and it is not acting on a purely inflammatory problem. Load management, calf and fascia stretching, and footwear address the tissue side. A licensed provider can advise where each option fits.
