Sissy,
Thanks for your reply, I do not have experience with Amitriptyline for PCS so i am glad for your advice.

sbosco,
My son had headaches but did not need to take anything else besides Ibuprofen, his symptoms were mostly dizziness, fatigue, and "being in a fog" as he kept describing it. I am sorry that you have to problem solve the headaches, because I am sure that is now the primary symtom and until that resolves, nothing else matters. I am sure it is also very difficult to get your son to describe his symtoms. this is part of the trouble, they cannot articulate for themselves how they are feeling. You start to have PCS yourself trying to get information from them. Bad headaches are however clearly obvious and so hard to have to watch your son suffer with. I hope the amitriptyline helps. Hopefully in time you can wean off of the meds and he will not have the headaches. Take care and take one day at a time.
