Severs? disease usually presents with pain in either one or both of a sufferer?s heels. The area can be sore or tender, particularly first thing in the morning or after squeezing. Because the pain is focussed on the heel, an important part of the foot that makes contact with the ground through virtually all movement, sufferers often have to limp to alleviate their discomfort. The pain of Severs? disease is at its worst after any exertion that involves contact between a heel and the ground, particularly strenuous exercise like running or sport. The condition is caused by the wear and tear of structures in the heel, most significantly the heel bone and any attached tendons. Severs? disease is prevalent in young children who are extremely active, particularly as the heel and its attached tendons are still growing in the age group the condition most commonly affects (7-14).
Sever?s disease is common, and typically occurs during a child?s growth spurt, which can occur between the ages of 10 and 15 in boys and between the ages of 8 and 13 in girls. Feet tend to grow more quickly than other parts of the body, and in most kids the heel has finished growing by the age of 15. Being active in sports or participating in an activity that requires standing for long periods can increase the risk of developing Sever?s disease. In some cases, Sever?s disease first becomes apparent after a child begins a new sport, or when a new sports season starts. Sports that are commonly associated with Sever?s disease include track, basketball, soccer, and gymnastics. Children who are overweight or obese are also at a greater risk of developing this condition. Certain foot problems can also increase the risk, including. Over pronating. Kids who over pronate (roll the foot inward) when walking may develop Sever?s disease. Flat foot or high arch. An arch that is too high or too low can put more stress on the foot and the heel, and increase the risk of Sever?s disease. Short leg. Children who have one leg that is shorter than the other may experience Sever?s disease in the foot of the shorter leg because that foot is under more stress when walking.
Symptoms of Sever?s disease, mostly pain at the back of heel, usually occur during and after sporting activity, and usually disappear with rest. In some cases, children may find it difficult to place pressure on their heels, and begin walking on their toes to gain relief. For some children, the heel pain will persist until the next morning, causing some stiffness or hobbling on first arising. Some children may experience mild swelling at the back of the heel.
Your Podiatrist or Physiotherapist will assist in diagnosing the injury and the extent of the damage. From this, they will develop a management plan which may include rest or activity modification, soft tissue treatment such as massage and stretching, correction of biomechanics through heel raises or orthoses and the progression through a series of specific strengthening exercises.
Non Surgical Treatment
There is nothing you can do to stop severs disease. It will stop when you finish growing. However the following will help to relieve the symptoms. Rest. Cut down on the time you spend playing sport until the pain has gone. Avoid sports that involve a lot of running or jumping. Swimming can be a useful alternative. Ice the affected area for ten to 15 minutes, especially after activity. Make sure you protect the skin by wrapping the ice in a towel. Elevate (raise) the leg when painful and swollen especially after sports. Pain relieving medication may reduce pain and swelling, but you need to discuss options with a pharmacist or GP. Always wear shoes. Avoid activities in bare feet. Choose a supportive shoe with the laces done up.
