Hello - My 23 Year Old Son Has Not Been

Hello - my 23 year old son has not been feeling well.., he complains that his neck hurts, his head feels heavy and he doesn't feel comfortable in his own body.., his hair looks dry and he says it's thinning. He is always tired - has been tested for thyroid disease and told he has it but just in the beginning stages so there is currently nothing they can do for him. He is thin and has stomach trouble when he eats anything too heavy. To me his symptoms suggest something more than thyroid disease. Please help!
