Growing pains may sound like an old wives' tale. In the case of Sever's (or Sever) disease, though, your child's growth spurt can lead to serious pain. It's not actually a disease but a heel injury.
The good news is that the condition doesn't cause any long-term foot problems. Symptoms typically go away after a few months.
The best treatment is simply rest. Your child will need to stop or cut down on sports until the pain gets better. When she's well enough to return to her sport, have her build up her playing time gradually.
Once your child's growth spurt ends, and she's reached full size, her Sever's disease won't return. Until then, the condition can happen again if your child stays very active.
