Hi i'm 14 and turning 15 in a few days but i've been noticing a slight lump forming under my left nipple and I am a male so I don't really see breast cancer as the problem. The other day I also started noticing blind spots in my eye fallowed by a bad headache and lately at night i've been hearing a sound almost like wind that seems to beat to the same rythym as my heart beat as well. Most of this can be traced back to puberty but i'm not sure if I should do anything about it or not. By the way i've realized the ear problem is probably pulsating tinnitus which can be realated to something as serious as a tumor or as little as an ear infection. I'm a little self-consciece and worried about talking to people about it so if it's nothing i'd rather not make a big deal out of it. Thanks!
