Calcaneal apophysitis (Sever's Disease) - although it's not an actual disease - is most often found in children. Calcaneal apophysitis is typically caused by trauma or overuse of growth plates in the heel. This condition is most often seen in children and usually comes from playing sports.  

Other potential causes of calcaneal apophysitis include obesity, a tight Achilles tendon, and foot deformities such as flatfoot or a high-arched foot.

Symptoms
- Pain in the back or bottom of the heel
- Limping
- Walking on toes
- Difficulty running, jumping, or participating in usual activities or sports
- Pain when the sides of the heel are squeezed

Treatment
- Staying off the injured foot
- Stretching exercises to help heal the inflamed tissue
- Heel cushions in the shoes or orthodics may be prescribed
- Medication to reduce pain and swelling including nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen

Preventative Measures:
- Avoiding obesity
- Wearing supportive footwear - consult with your doctor for recommended footwear
- Avoiding or limiting wearing of cleated athletic shoes
- Avoiding strenuous activity
