Sever?s Disease is one of the most common overuse sports injuries in the U.S. It may not receive the street cred that plantar fasciitis gets, but this painful condition affecting the heel routinely affects child athletes, usually from eight to thirteen years of age, right when the bones are coming together. The pounding force causes inflammation between the bones, according to YNN, as well as injury to the growth plates themselves. While the ?disease? classification may sound scary, it?s actually a quite normal overuse sports injury that does not typically persist into adulthood.
During the growth spurt of early puberty, the bones often grow faster than the leg muscles and tendons. This can cause the muscles to become very tight and overstretched, the heel becomes less flexible and this build-up of pressure can result in redness, swelling, tenderness and pain at the heel.
Sharp pain will be present in the affected heel (or both heels), especially while running or walking. Pain can be heightened following activity. The area will be tender to the touch and usually becomes inflamed or reddened. It may also be painful to press on the heel with a finger from the back or to squeeze the sides together; the latter is particularly common. You might notice stiffness in some of the surrounding muscles, making regular movements more difficult to achieve. This and the pain can manifest physically in abnormal practices like tiptoeing or limping. In some cases a lump can be detected on the back of the heel, though it may be so small as to defy detection.
A physical exam of the heel will show tenderness over the back of the heel but not in the Achilles tendon or plantar fascia. There may be tightness in the calf muscle, which contributes to tension on the heel. The tendons in the heel get stretched more in patients with flat feet. There is greater impact force on the heels of athletes with a high-arched, rigid foot.
Non Surgical Treatment
The following are different treatment options Rest and modify activity. Limit running and high-impact activity to rest the heel and lessen the pain. Choose one running or jumping sport to play at a time. Substitute low-impact cross-training activities to maintain cardiovascular fitness. This can include biking, swimming, using a stair-climber or elliptical machine, rowing, or inline skating. Reduce inflammation. Ice for at least 20 minutes after activity or when pain increases. Nonsteroidal anti-inflammatory drugs (NSAIDs) may also help. Stretch the calf. Increase calf flexibility by doing calf stretches for 30 to 45 seconds several times per day. Protect the heel. The shoe may need to be modified to provide the proper heel lift or arch support. Select a shoe with good arch support and heel lift if possible. Try heel lifts or heel cups in sports shoes, especially cleats. Try arch support in cleats if flat feet contribute to the problem. Take it one step at a time. Gradually resume running and impact activities as symptoms allow. Sever?s disease usually goes away when the growth plate (apophysis) matures, which should be by age 12 to 13 years in females and 13 to 14 years in males.
Sever's disease may be prevented by maintaining good joint and muscle flexibility in the years leading up to, and during, their growth spurts (eg girls 8 to 10, boys 10 to 12). Foot arch problems such as flat feet should be addressed after the age of five if they don't appear to be self-correcting. If you are concerned, please ask your health practitioner. The most important factor is the amount of weight-bearing exercise your child is currently performing.
