At the bottom of your foot there’s a thick band of connective tissue called the plantar fascia or arch tendon. It connects your heel bone (calcaneus) to the front of your foot. If the plantar fascia becomes irritated and sore from overuse, it’s known as plantar fasciitis. Plantar fasciitis sometimes can be mistaken for heel spurs, which is a different kind of injury with similar symptoms. Plantar fasciitis is a common cause of heel pain in runners, dancers, and athletes in sports that involve a lot of running or jumping. You don’t have to be active to get plantar fasciitis. It can affect anyone. People who are overweight, pregnant women, people whose jobs involve a lot of standing, and people who wear worn-out shoes all have a higher chance of getting plantar fasciitis.
Plantar fasciitis can be confused with a condition called tarsal tunnel syndrome. In tarsal tunnel syndrome, an important nerve in the foot, the tibial nerve, is trapped and pinched as it passes through the tarsal tunnel, a condition analogous to carpal tunnel syndrome in the wrist. This may cause symptoms similar to the pain of a plantar fasciitis. There are also other less common problems such as nerve entrapments, stress fractures, and fat pad necrosis, all of which can cause foot pain. Finally, several rheumatologic conditions can cause heel pain. These syndromes such as Reiter’s syndrome and ankylosing spondylitis can cause heel pain similar to plantar fasciitis. If your symptoms are not typical for plantar fasciitis, or if your symptoms do not resolve with treatment, your doctor will consider these possible diagnoses.
Most people with plantar fasciitis have pain when they take their first steps after they get out of bed or sit for a long time. You may have less stiffness and pain after you take a few steps. But your foot may hurt more as the day goes on. It may hurt the most when you climb stairs or after you stand for a long time. If you have foot pain at night, you may have a different problem, such as arthritis , or a nerve problem such as tarsal tunnel syndrome.
A thorough subjective and objective examination from a physiotherapist is usually sufficient to diagnose plantar fasciitis. Occasionally, further investigations such as an X-ray, ultrasound or MRI may be required to assist with diagnosis and assess the severity of the condition.
Non Surgical Treatment
Many types of treatment have been used to combat plantar fasciitis, including injections, anti-inflammatory medications, orthotics, taping, manipulation, night splinting, and instrument-assisted soft-tissue manipulation (IASTM). IASTM begins with heat, followed by stretching. Stretching may be enhanced by applying ice to the plantar fascia. These stretches should be performed several times per day, with the calf in the stretched position. IASTM uses stainless-steel instruments to effectively access small areas of the foot. IASTM is believed to cause a secondary trauma to injured soft tissues as part of the healing process. Therapeutic modalities such as low-level laser, ultrasound, and electrical muscular stimulation may be effective in the reduction of pain and inflammation. Low Dye strapping or taping of the foot is an essential part of successful treatment of plantar fasciitis. Extracorporeal shock-wave therapy (ESWT) was introduced with great promise at one time. Recent studies have reported less favorable results. Some report no effect. Previous local steroid injection may actually have a negative effect on results from ESWT.
Plantar fasciotomy is often considered after conservative treatment has failed to resolve the issue after six months and is viewed as a last resort. Minimally invasive and endoscopic approaches to plantar fasciotomy exist but require a specialist who is familiar with certain equipment. Heel spur removal during plantar fasciotomy has not been found to improve the surgical outcome. Plantar heel pain may occur for multiple reasons and release of the lateral plantar nerve branch may be performed alongside the plantar fasciotomy in select cases. Possible complications of plantar fasciotomy include nerve injury, instability of the medial longitudinal arch of the foot, fracture of the calcaneus, prolonged recovery time, infection, rupture of the plantar fascia, and failure to improve the pain. Coblation (TOPAZ) surgery has recently been proposed as alternative surgical approaches for the treatment of recalcitrant plantar fasciitis.
Plantar fasciitis can be a nagging problem, which gets worse and more difficult to treat the longer it’s present. To prevent plantar fasciitis, run on soft surfaces, keep mileage increases to less than 10 percent per week, and visit a specialty running shop to make sure you’re wearing the proper shoes for your foot type and gait. It’s also important to stretch the plantar fascia and Achilles tendon.
