The plantar fascia is a thickened fibrous aponeurosis that originates from the medial tubercle of the calcaneus, runs forward to insert into the deep, short transverse ligaments of the metatarsal heads, dividing into 5 digital bands at the metatarsophalangeal joints and continuing forward to form the fibrous flexor sheathes on the plantar aspect of the toes. Small plantar nerves are invested in and around the plantar fascia, acting to register and mediate pain.
Excessive stretching of the plantar fascia can result in microtrauma of this structure either along its course or where it inserts onto the medial calcaneal tuberosity. This microtrauma, if repetitive, can result in chronic degeneration of the plantar fascia fibers. The loading of the degenerative and healing tissue at the plantar fascia may cause significant plantar pain, particularly with the first few steps after sleep or other periods of inactivity. The term fasciitis may, in fact, be something of a misnomer, because the disease is actually a degenerative process that occurs with or without inflammatory changes, which may include fibroblastic proliferation. This has been proven from biopsies of fascia from people undergoing surgery for plantar fascia release.
Plantar fasciitis typically causes a stabbing pain in the bottom of your foot near the heel. The pain is usually worst with the first few steps after awakening, although it can also be triggered by long periods of standing or getting up from a seated position.
Your doctor may look at your feet and watch the way you stand, walk and exercise. He can also ask you questions about your health history, including illnesses and injuries that you had in your past. The symptoms you have such as the pain location or when does your foot hurts most. Your activity routine such as your job, exercise habits and physical activities preformed. Your doctor may decide to use an X-ray of your foot to detect bones problems. MRI or ultrasound can also be used as further investigation of the foot condition.
Non Surgical Treatment
Rest the foot as much as you can, especially during the beginning of the treatment. Try to avoid unnecessary foot activity like running, or excess standing. Instead, perform exercises that do not put stress on the injured foot, like bicycling or swimming. Apply ice to the painful area a few times a day to reduce inflammation. Try rolling the arch of the foot over a tennis ball or a baseball. A good treatment is rolling the arch of the foot over a frozen soft drink can. This exercise cools and stretches the affected area. You can use over-the-counter pain relievers (ibuprofen, naproxen) to reduce pain and inflammation. Use an over-the-counter arch support or heel support. Avoid walking barefoot, because it may add stress on the plantar fascia. Exercise your feet to make the muscles, ligaments, tendons and other parts stronger. Stronger foot muscles give better support to the plantar fascia preventing it from another injury. Stretching the foot, the plantar fascia and the calf muscles a few times a day is an essential part of treatment and prevention.
When more-conservative measures aren’t working, your doctor might recommend steroid shots. Injecting a type of steroid medication into the tender area can provide temporary pain relief. Multiple injections aren’t recommended because they can weaken your plantar fascia and possibly cause it to rupture, as well as shrink the fat pad covering your heel bone. Extracorporeal shock wave therapy. In this procedure, sound waves are directed at the area of heel pain to stimulate healing. It’s usually used for chronic plantar fasciitis that hasn’t responded to more-conservative treatments. This procedure may cause bruises, swelling, pain, numbness or tingling and has not been shown to be consistently effective. Surgery. Few people need surgery to detach the plantar fascia from the heel bone. It’s generally an option only when the pain is severe and all else fails. Side effects include a weakening of the arch in your foot.
You can help to prevent plantar fasciitis by maintaining a healthy weight, by warming up before participating in sports and by wearing shoes that support the arch and cushion the heel. In people who are prone to episodes of plantar fasciitis, exercises that stretch the heel cord (known as the Achilles tendon) and the plantar fascia may help to prevent plantar fasciitis from returning. Ice massage also can be used on the bottom of the foot after stressful athletic activities. It is possible that strict control of blood sugar will prevent plantar fasciitis in people with diabetes, although this has not been proven.
