Overview
Heel pain is a very common foot problem. The sufferer usually feels pain either under the heel (planter fasciitis) or just behind it (Achilles tendinitis), where the Achilles tendon connects to the heel bone. Even though Heel Pain can be severe and sometimes disabling, it is rarely a health threat. Heel pain is typically mild and usually disappears on its own, however, in some cases the pain may persist and become chronic (long-term). There are 26 bones in the human foot, of which the heel (calcaneus) is the largest. The human heel is designed to provide a rigid support for the weight of the body. When we are walking or running it absorbs the impact of the foot when it hits the ground, and springs us forward into our next stride. Experts say that the stress placed on a foot when walking may be 1.25 times our body weight, and 2.75 times when running. Consequently, the heel is vulnerable to damage, and ultimately pain.
Causes
In the majority of cases, heel pain has a mechanical cause. It may also be caused by arthritis, infection, an autoimmune problem trauma, a neurological problem, or some other systemic condition (condition that affects the whole body).
Symptoms
Both heel pain and heel spurs are frequently associated with an inflammation of the long band of tissue that connects the heel and the ball of the foot. The inflammation of this arch area is called plantar fasciitis. The inflammation maybe aggravated by shoes that lack appropriate support and by the chronic irritation that sometimes accompanies an athletic lifestyle. Achilles Tendinopathy, Pain and inflammation of the tendon at the back of the heel that connects the calf muscle to the foot. Sever?s, Often found in children between the ages of 8 – 13 years and is an inflammation of the calcaneal epiphyseal plate (growth plate) in the back of the heel. Bursitis, An inflamed bursa is a small irritated sack of fluid at the back of the heel. Other types of heel pain include soft tissue growths, Haglunds deformity (bone enlargement at the back of the heel), bruises or stress fractures and possible nerve entrapment.
Diagnosis
A podiatrist (doctor who specializes in the evaluation and treatment of foot diseases) will carry out a physical examination, and ask pertinent questions about the pain. The doctor will also ask the patient how much walking and standing the patient does, what type of footwear is worn, and details of the his/her medical history. Often this is enough to make a diagnosis. Sometimes further diagnostic tests are needed, such as blood tests and imaging scans.
Non Surgical Treatment
Most patients get better with the help of nonsurgical treatments. Stretches for the calf muscles on the back of the lower leg take tension off the plantar fascia. A night splint can be worn while you sleep. The night splint keeps your foot from bending downward. It places a mild stretch on the calf muscles and the plantar fascia. Some people seem to get better faster when using a night splint. They report having less heel pain when placing the sore foot on the ground in the morning. There have been a few studies that reported no significant benefit from adding night splinting to a program of antiinflammatory meds and stretching. Other studies report the benefits of short-term casting to unload the heel, immobilize the plantar fascia, and reduce repetitive microtrauma. Supporting the arch with a well fitted arch support, or orthotic, may also help reduce pressure on the plantar fascia. Placing a special type of insert into the shoe, called a heel cup, can reduce the pressure on the sore area. Wearing a silicone heel pad adds cushion to a heel that has lost some of the fat pad through degeneration. Shock wave therapy is a newer form of nonsurgical treatment. It uses a machine to generate shock wave pulses to the sore area. Patients generally receive the treatment once each week for up to three weeks. It is not known exactly why it works for plantar fasciitis. It’s possible that the shock waves disrupt the plantar fascial tissue enough to start a healing response. The resulting release of local growth factors and stem cells causes an increase in blood flow to the area. Recent studies indicate that this form of treatment can help ease pain, while improving range of motion and function.
Surgical Treatment
Surgery is a last resort in the treatment of heel pain. Physicians have developed many procedures in the last 100 years to try to cure heel pain. Most procedures that are commonly used today focus on several areas, remove the bone spur (if one is present), release the plantar fascia (plantar fasciotomy), release pressure on the small nerves in the area. Usually the procedure is done through a small incision on the inside edge of the foot, although some surgeons now perform this type of surgery using an endoscope. An endoscope is a tiny TV camera that can be inserted into a joint or under the skin to allow the surgeon to see the structures involved in the surgery. By using the endoscope, a surgeon can complete the surgery with a smaller incision and presumably less damage to normal tissues. It is unclear whether an endoscopic procedure for this condition is better than the traditional small incision. Surgery usually involves identifying the area where the plantar fascia attaches to the heel and releasing the fascia partially from the bone. If a small spur is present this is removed. The small nerves that travel under the plantar fascia are identified and released from anything that seems to be causing pressure on the nerves. This surgery can usually be done on an outpatient basis. This means you can leave the hospital the same day.
Prevention
Being overweight can place excess pressure and strain on your feet, particularly on your heels. Losing weight, and maintaining a healthy weight by combining regular exercise with a healthy, balanced diet, can be beneficial for your feet. Wearing appropriate footwear is also important. Ideally, you should wear shoes with a low to moderate heel that supports and cushions your arches and heels. Avoid wearing shoes with no heels.
