Your buldging veins are most likely the result of several factors, genetics, the fact that you are thin, that you are well hydrated and that your cardiovascular status is good. There is really no treatment for such a problem, however to minimize this if you hold your hands up the veins will temporarily become minimized. Sorry I can't be of more help... I do understand your situation.
