My question is concerning my son, who has a left leg that has not developed as well as the other one, and he has had symtoms that continue to arise over a period of time. This leg condition began during his 11th year and he complained of pain that is chronic and will not go away, he has lost weight since this time and is about 5 6 and weighs about 100lbs. he will not eat very much, and gets allergic to foods easily that swell his mouth (lips) so he will not eat, he will not eat any more melons because they begin to swell his throat, and he is tired alot, does not want to run or play outside any more, and new systom is now he is beginning to have nose bleeds often...i am scared and not sure what doctor to see next because nobody will give me a straight answer.
