Plantar fasciitis is a painful condition causing heel pain and many people with the condition also have heel spurs. It affects the band of tissue (plantar fascia) that supports the middle part of the foot and runs along the sole of the foot from the heel to the ball of the foot. Usually the plantar fascia is strong and flexible but due to certain factors it can become irritated and inflamed where the plantar fascia joins the bone in the foot. Heel spurs occur when there’s constant pulling of the fascia at the heel bone. This leads to a bony growth or spur. The symptoms of plantar fasciitis are pain in the arch of the foot or heel. This pain is usually worse in the morning after rest when the plantar fascia tightens and shortens. Heel spurs cause a stabbing pain at the bottom or front of the heel bone.
There are a number of plantar fasciitis causes. The plantar fascia ligament is like a rubber band and loosens and contracts with movement. It also absorbs significant weight and pressure. Because of this function, plantar fasciitis can easily occur from a number of reasons. Among the most common is an overload of physical activity or exercise. Athletes are particularly prone to plantar fasciitis and commonly suffer from it. Excessive running, jumping, or other activities can easily place repetitive or excessive stress on the tissue and lead to tears and inflammation, resulting in moderate to severe pain. Athletes who change or increase the difficulty of their exercise routines are also prone to overdoing it and causing damage. Another common cause of plantar fasciitis is arthritis. Certain types of arthritis can cause inflammation to develop in tendons, resulting in plantar fasciitis. This cause is particularly common among elderly patients. Diabetes is also a factor that can contribute to further heel pain and damage, particularly among the elderly. Among the most popular factors that contribute to plantar fasciitis is wearing incorrect shoes. In many cases, shoes either do not fit properly, or provide inadequate support or cushioning. While walking or exercising in improper shoes, weight distribution becomes impaired, and significantly stress can be added to the plantar fascia ligament.
Plantar fasciitis is characterized by the following signs and symptoms. Acute plantar fasciitis, pain is usually worse in the morning but may improve when activity continues; if the plantar fasciitis is severe, activity will exacerbate the pain, pain will worsen during the day and may radiate to calf or forefoot, pain may be described anywhere from “minor pulling” sensation, to “burning”, or to “knife-like”, the plantar fascia may be taut or thickened, passive stretching of the plantar fascia or the patient standing on their toes may exacerbate symptoms, acute tenderness deep in the heel-pad along the insertion of the plantar aponeurosis at the medial calcaneal tuberosity and along the length of the plantar fascia, may have localized swelling. Chronic plantar fasciitis, plantar fasciitis is classified as “chronic” if it has not resolved after six months, pain occurs more distally along the aponeurosis and spreads into the Achilles tendon.
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
A change to properly fitting, appropriate shoes may be useful in some patients. Some individuals wear shoes that are too small, which can exacerbate many types of foot pain. Patients often find that wearing shoes with thicker, well-cushioned midsoles, usually made of a material like high-density ethylene vinyl acetate (such as is found in many running shoes), decreases the pain associated with long periods of walking or standing. Studies have shown that with age, running shoes lose a significant portion of their shock absorption. Thus, simply getting a new pair of shoes may be helpful in decreasing pain. For individuals with flat feet, motion control shoes or shoes with better longitudinal arch support may decrease the pain associated with long periods of walking or standing. Motion control shoes usually have the following characteristics: a straight last, board or combination lasted construction, an external heel counter, a wider flare and extra medial support. A change in shoes was cited by 14 percent of patients with plantar fasciitis as the treatment that worked best for them.
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.
Stretching your plantar fasciitis is something you can do at home to relieve pain and speed healing. Ice massage performed three to four times per day in 15 to 20 minute intervals is also something you can do to reduce inflammation and pain. Placing arch supports in your shoes absorbs shock and takes pressure off the plantar fascia.
