For the past year, I have had an issue with my upper arm/front armpit. Its not really my armpit, its the place people call "armpit fat" that pinches. Well, I've never had a problem with that because I'm really small but for the last year, I haven't been able to wear anything that rubs or touches that spot. It doesn't hurt, its just beyond annoying. I can feel every stitch on any clothing. At first, I switched from regular bras to sports bras and that helped but then that became annoying so I switched to tank tops under loose tops and that worked. Now, even the tank tops are annoying me. There doesn't appear to be any swelling so I don't think its the lymph node. I thought maybe I should just tighten it with exercise so I started doing push ups but after a long period time, its not helping and only making my arms tighter. I only have this problem on my right side, by the way. I've had my bra sized twice to make sure that wasn't the problem as well. I've been taking adderall for three years daily. its driving me crazy- please help!
