Looking Beyond Traditional Surgery for Neuromas and Plantar Fasciitis

Chronic heel pain and nerve-related foot pain can make everyday activities difficult, limiting a person’s ability to walk, exercise, or even stand comfortably. Two of the most common causes are plantar fasciitis and Morton’s neuroma. Although surgery is sometimes recommended when conservative care fails, board-certified podiatrist Dr. Alan Shih of Head to Toe Healthcare, PLC believes many patients benefit from considering less invasive options before proceeding with more aggressive procedures.

Plantar fasciitis develops when the thick band of connective tissue along the bottom of the foot becomes irritated and inflamed. The condition is frequently associated with poor foot mechanics, prolonged standing, excess strain on the feet, or wearing shoes that fail to provide adequate support. While many patients improve with stretching, orthotics, physical therapy, or other conservative treatments, persistent cases often lead to discussions about surgery.

One commonly performed procedure involves partially releasing the plantar fascia to reduce tension. However, Dr. Shih points out that this tissue serves an important structural purpose by supporting the arch of the foot. Cutting part of the plantar fascia may relieve pain for some individuals, but it can also reduce the natural stability of the foot and increase stress on the remaining tissues. He also notes that although heel spurs are frequently seen on X-rays, they are not always the primary source of heel pain and should not automatically determine the treatment plan.

Morton’s neuroma presents a different challenge. This painful condition typically develops between the third and fourth toes when a nerve becomes compressed and irritated. Symptoms often include burning pain, numbness, tingling, or the sensation of standing on a small pebble inside the shoe. Initial treatment commonly includes shoe modifications, custom orthotics, activity changes, and corticosteroid injections. Unfortunately, some patients continue to experience ongoing discomfort despite these measures.

Rather than immediately removing the affected nerve, Dr. Shih favors preserving its natural anatomy whenever possible. He frequently recommends nerve decompression, a procedure designed to relieve the pressure surrounding the nerve without removing it. By eliminating the source of compression, the nerve is given the opportunity to function more normally while avoiding some of the potential complications associated with nerve excision, including the development of painful stump neuromas.

“I don’t oppose surgery,” Dr. Shih explains. “The key is selecting the procedure that best preserves normal anatomy and function whenever possible.”

In addition to surgical decompression, Dr. Shih also utilizes Radiofrequency Ablation (RFA) for carefully selected patients suffering from chronic plantar fasciitis or neuroma pain. RFA has been used for years in pain management and works by delivering controlled radiofrequency energy to interrupt the transmission of pain signals from specific sensory nerves.

Because the treatment targets pain-carrying sensory fibers with precision, it differs from broader destructive techniques that may affect both sensory and motor nerves. Preserving motor nerve function is important because these nerves control muscle activity, helping maintain normal strength, balance, and foot mechanics. By focusing on the nerves responsible for pain, RFA offers a minimally invasive option with relatively little downtime, allowing many patients to return to normal activities quickly.

For individuals who have struggled with chronic foot pain despite traditional therapies, these newer treatment strategies may provide additional options before considering more extensive surgical procedures. Every patient requires an individualized evaluation, but preserving normal anatomy while minimizing unnecessary tissue disruption remains a guiding principle in Dr. Shih’s approach to care.

As technology continues to advance and minimally invasive techniques become more refined, treatments such as nerve decompression and Radiofrequency Ablation are expanding the range of options available for patients seeking lasting relief from plantar fasciitis and Morton’s neuroma without compromising long-term foot function.
