My grandson is 11 years old is having pain in the legs bottom knee portion for the past 5 months. He is not able to go the school daily. He takes 5 or 6 days rest and attend one day, His friends will touch/hit the legs and will return crying. Again will not attend class for few days. This repeats. We have shown to physiotherapists, orthopediatricians and many other doctors. All tests including MRI has been done. Everything is normal. Doctors are saying the bones are growing and there is a gap which will close slowly. It may take 6 months or so. There is nothing we can do? Let him attend classes. But he is suffering from pain. What can we do now?
