i head read that if it was glands then it would be hard or feel like marbles or somthin of that sort under the skin, mine just get very soft at the bottom outsides of my pecs and then the nipples pushes out in the pictures, I guess i dont let it affect me that much, i have my shirt of like 80% of chances i get and i work as a lifguard in the summers, its just somthing that everytime i look down it bothers me, moslty like i said, because i DO workout VERY HARD about 5-6 times every week, i love lifting and lately ive been running about 1-2 miles a day, and yet i still have that to look down and see those annyoing little SH ITS.
