Plantar fasciitis is a common, painful foot condition. Patients, and sometimes doctors often confuse the terms plantar fasciitis and heel spurs. Plantar fasciitis refers to the syndrome of inflammation of the band of tissue that runs from the heel along the arch of the foot; a heel spur is a hook of bone that can form on the heel bone (calcaneus). About 70% of patients with plantar fasciitis have been noted to have a heel spur that can be seen on x-ray. Plantar fasciitis is most often seen in middle-aged men and women, but can be found in all age groups. The condition is diagnosed with the classic symptoms of pain well focused deep in the heel area of the bottom of the foot. Often the pain from plantar fasciitis is most severe when you first stand on your feet in the morning. Pain often subsides quite quickly, but then returns after prolonged standing or walking. Plantar fasciitis is sometimes, but not always, associated with a rapid gain of weight. It is also sometimes seen in recreational athletes, especially runners. In these athletes, it is thought that the repetitive nature of the sports causes the damage to the fibrous tissue that forms the arch of the foot.
It usually starts following an increase in activity levels. Increase in weight. Standing for long periods. Poor footwear. Tight muscle groups. Abnormal pressure on the plantar Fascia can be caused by any of the above. The plantar fascia becomes inflamed and tiny rips can occur where it attaches into the inside of the heel bone. The area becomes inflamed and swollen, and it is the increase in fluid to the area that accumulates when weight is taken off the area that then causes the pain on standing.
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.
Your GP or podiatrist (a healthcare professional who specialises in foot care) may be able to diagnose the cause of your heel pain by asking about your symptoms and examining your heel and foot. You will usually only need further tests if you have additional symptoms that suggest the cause of your heel pain is not inflammation, such as numbness or a tingling sensation in your foot, this could be a sign of nerve damage in your feet and legs (peripheral neuropathy) your foot feels hot and you have a high temperature (fever) of 38C (100.4F) or above – these could be signs of a bone infection, you have stiffness and swelling in your heel, this could be a sign of arthritis. Possible further tests may include blood tests, X-rays – where small doses of radiation are used to detect problems with your bones and tissues, a magnetic resonance imaging (MRI) scan or ultrasound scan, which are more detailed scans.
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.
Surgery is not a common treatment for this condition. Approximately 5% of people with plantar fasciitis require surgery if non-surgical methods do not help to relieve pain within a year. The surgical procedure involves making an incision in the plantar fascia in order to decrease the tension of the ligament. Potential risks of this surgical procedure include irritation of the nerves around the heel, continued plantar fasciitis, heel or foot pain, infection, flattening of the arch, problems relating to the anesthetic.
Making sure your ankle, Achilles tendon, and calf muscles are flexible can help prevent plantar fasciitis. Stretch your plantar fascia in the morning before you get out of bed. Doing activities in moderation can also help.
