My 16 year old son started having severe back pain in Sept. '11. He was diagnosed with mild scoliosis. He saw a Dr. who told us that it is very minor and should not cause him much pain. After this the pain has not gotten better, and he has now lost 15 lbs. and has no appetite. He is down to 145 at 6' tall. He only has a bm after taking a stool softener and he is always exhausted. He also has a spot on his lung that the Ped said was probably histoplasmosis since we live in the Mississippi Delta area. He has a referral for a GI specialist at LeBonheur Children's Hospital next week. I am just hoping someone reads these symptoms and can offer me some clues.
