Plantar fasciitis is sometimes mixed up with a heel spur although they are not the same. A heel spur is a calcium deposit that occurs where the plantar fascia is attached to the heel bone (calcaneus). In many cases a heel spur is found on a foot with no pain or other symptoms at all. And in many painful heels there is no sign for a heel spur. Heel spur and painful heal does not necessarily go together. For many years plantar fasciitis was believed to be an inflammatory condition. It is thought now to be inaccurate because there were many cases of the disorder with no inflammatory signs observed within the fascia. The heel pain cause is now believed to be damage to the collagen fibers of the fascia. This damage, caused by stress injury, sometimes may include inflammatory cells.
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.
Plantar fasciitis commonly causes a stabbing pain in the heel of the foot, which is worse during the first few steps of the day after awakening. As you continue to walk on the affected foot, the pain gradually lessens. Usually, only one foot is affected, but it can occur in both feet simultaneously.
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
Cortisone is a powerful anti-inflammatory and when injected directly into the heel it will work almost immediately. Bear in mind however, that the treatment does not address the root cause of the inflammation, and needs to be repeated every few months. Also note, these injections are quite painful, and most doctors today will consider other, less invasive treatment options first. ESWT (Extra Corporeal Shockwave Treatment). A specialist targets therapeutic shockwaves to the affected heel area. This will stimulate a healing response in the affected tissue and ligaments, resulting in reduced inflammation and pain. This treatment and may take from 3 to 4 months to be fully effective. Extracorpreal Shock Wave Therapy is the latest technology to treat chronic plantar fasciitis. It is a non-invasive treatment and highly recommended for people who have tried other treatment like cortisone-injections, accupuncture etc with little or no success. Electroacupuncture and standard acupuncture are used in the treatment of plantar fasciitis and other foot problems such as neuromas and nerve impingement, numbness in the toes etc. In some cases there is nerve entrapment within the foot combined with referred pain from other areas of the body. Some research suggests that acunpuncture can be effective in the treatment of heel pain. A trigger point is an irritable knot in the muscle tissue. When pressed trigger points are very tender and can cause pain in that specific spot or elsewhere in the body (referred pain). The response to pushing into the knot is a muscle twitch. The foot contains 126 muscles, tendons and ligaments, so there are plenty of ‘hiding places’ for trigger points. Trigger points in the calf muscles often refer pain directly to the bottom of the foot. Trigger point therapy of the lower leg and foot can therefore be successful in the treatment of plantar fasciitis.
Most studies indicate that 95% of those afflicted with plantar fasciitis are able to relieve their heel pain with nonsurgical treatments. If you are one of the few people whose symptoms don’t improve with other treatments, your doctor may recommend plantar fascia release surgery. Plantar fascia release involves cutting part of the plantar fascia ligament in order to release the tension and relieve the inflammation of the ligament. Overall, the success rate of surgical release is 70 to 90 percent in patients with plantar fasciitis. While the success rate is very high following surgery, one should be aware that there is often a prolonged postoperative period of discomfort similar to the discomfort experienced prior to surgery. This pain usually will abate within 2-3 months. One should always be sure to understand all the risks associated with any surgery they are considering.
