i am a competitive gymnast with osgood sclatters disease – it’s spreading
hi that looks like a separate issue may be there is no relation between your knee pain and your loss of appetite and fatigue… if your knee is locking out. you should see an orthopedist to exclude a torn/injured meniscus. otherwise you can make some laboratory investigations as cbc and esr to rule out other pathology if found. do your knees become hot? is it one or both knees? what aggravates the pain?
