Vitamin B plus NSAIDs for heel pain: what the new trial means for plantar fasciitis

Intro

A recent multicentre randomised trial from Korea tested whether adding a vitamin B complex to an oral non-steroidal anti-inflammatory drug improved outcomes for people with painful foot and ankle conditions. After four weeks the group taking aceclofenac plus vitamin B had larger drops in pain and bigger improvements in function than the group taking aceclofenac alone. The effect was clearest for people with longer standing problems and for conditions that include plantar fasciitis. We'll explain what that means for heel pain on the Central Coast and how we'd use it in clinic.

What we see

Patients with plantar heel pain and plantar fasciitis commonly present with a few patterns: pain first steps after rest, sharp medial heel pain with running or school sport, or a more diffuse aching after long standing or netball. Some people have sharp, shooting symptoms suggesting nerve involvement, which we see with Morton's neuroma or irritated plantar nerves. On assessment we often find reduced load tolerance , they can't tolerate normal training volume without pain , along with tight calves, weak intrinsic foot muscles, and altered pressure patterns under the forefoot or heel.

Why it's happening

Heel pain is rarely one simple thing. Plantar fasciitis is driven by repetitive overload of the plantar fascia insertion, often with calf tightness and high plantar pressures. Chronic cases develop local tissue changes and sometimes nerve sensitisation. Anti-inflammatory medication can reduce pain, but it does not change the mechanical load causing the problem. The trial suggests vitamin B complex given with an NSAID can amplify short-term pain relief. That fits with mechanisms where B vitamins support nerve health and modulate pain pathways, which may be helpful where nerve irritation or chronic sensitisation is part of the picture.

What we test

We focus on tests that identify what's driving the load and pain. In clinic we look at:

• gait and running mechanics, including stride, heel strike and forefoot loading during running or jogging,
• calf length and strength, single-leg heel raise capacity, and intrinsic foot muscle strength,
• plantar pressure patterns if needed (we use treadmill pressure analysis when a clearer picture of load is helpful),
• tenderness at the plantar fascia origin and sensitivity tests when nerve involvement is suspected,
• load tolerance: how much walking, running or standing produces pain and how quickly symptoms come back.

These tests tell us whether pain is primarily mechanical, inflammatory, neuropathic, or a mix.

What actually changes it

The trial shows a combination of aceclofenac and vitamin B complex produced a greater short-term reduction in pain (average VAS drop roughly 2.9 points vs 0.9 points after 4 weeks) and improved quality of life and foot function scores. That is meaningful for many people, especially those with symptoms longer than three months or conditions like plantar fasciitis and Morton's neuroma. But medication and supplements are tools, not fixes. In clinic we use short-term pain relief strategically: to bring pain down enough for people to tolerate progressive loading and rehab. The things that change long-term outcomes are load management and progressive strengthening: graded calf and plantar fascia loading, improving single-leg calf capacity, correcting training errors, and managing footwear and running surfaces. In some patients an in-shoe orthosis or temporary shoe change reduces peak plantar pressures so rehab can progress. If pain is primarily neuropathic, the vitamin B effect may be more helpful; if pain is purely mechanical, the benefit from vitamins is likely smaller.

How that fits into heel pain treatment

If someone presents with running heel pain or chronic plantar heel pain we usually combine approaches:

• immediate: reduce the offending load , cut out hill repeats, reduce mileage, switch to cross training until pain falls,
• analgesia as needed and after medical review: short courses of NSAIDs can help symptoms; this trial suggests adding a vitamin B complex may give extra short-term relief for some patients,
• rehab: progressive calf eccentric and heavy slow resistance exercises, plantar fascia loading protocols, and intrinsic foot strengthening,
• footwear and orthoses: adjust cushioning and medial support if pressure patterns or mechanics warrant it,
• review: monitor progress and adapt load every 1 to 2 weeks using pain-guided progression rather than fixed timelines.

We do not expect vitamin B plus NSAIDs to replace these steps. Instead, they can be used to reduce pain enough to allow meaningful rehab and load progression.

What people get wrong

People often reach for pills or complete rest and expect the problem to disappear. Rest alone reduces symptoms briefly but does not restore load tolerance. Another common mistake is assuming all heel pain is plantar fasciitis; if nerve pain or forefoot loading is the driver the strategy differs. Some patients take random vitamin B supplements without knowing formulation or dose; the trial used a specified vitamin B complex alongside aceclofenac for four weeks, and results cannot be generalised to all over-the-counter combinations. Also, long-term reliance on NSAIDs without medical oversight risks side effects; any medication plan should be discussed with a GP or treating doctor.

When to get help or consider medication changes

Seek prompt review if you have: progressive worsening, severe pain at night, numbness or weakness, inability to weight-bear, or no improvement after a period of structured conservative care. If you are thinking about combining NSAIDs and vitamin B, check medical suitability first. In clinic we discuss coordination with the patient's GP or the prescribing physician, especially for people with a history of stomach ulcers, kidney disease, or those on multiple medications.

A practical example from clinic

We had a middle-aged runner from the Central Coast with eight months of medial heel pain worse first steps and after speedy park runs. He could not progress calf loading without flaring pain. After discussing options with his GP, a short four-week course of an NSAID with a vitamin B complex was started to help pain control. That allowed us to progress heavy slow resistance loading for the calf and plantar fascia and reduce running volume safely. Over three months his load tolerance improved and he returned to regular training with better mechanics and less flare. The medication and vitamin were a bridge, not a cure.

Bottom line

The trial shows adding vitamin B complex to an NSAID produced larger short-term reductions in pain and better function for several foot and ankle conditions, including plantar fasciitis, especially when symptoms were chronic. In clinic we see this as a potentially useful adjunct to enable rehab. The lasting change still comes from addressing load, strength and pressure patterns. Discuss any medication or supplement plan with your GP, and if you're on the Central Coast and struggling with heel pain bring in a recent training log and your shoes so we can assess load and start a progressive plan.

Trial snapshot

• Design: multicentre randomized controlled trial
• Participants: 201 enrolled, 156 completed analysis
• Intervention: aceclofenac 100 mg twice daily with or without vitamin B complex for 4 weeks
• Key result: mean VAS pain drop ~2.9 points with combination versus ~0.9 with NSAID alone; larger functional and quality of life gains in the combination group
