Hi, My left side of breast is a lot bigger than the right side. So much so that it is highly visible and I feel extremely under confident while wearing tight fitted clothes. Also, it aches almost all the time. I've some problem in lifting my left hand because the muscle really aches in my underarms and upper arms. I also have really bad ache in my left shoulder blade and the area around it. It gets pretty uncomfortable to sleep on my left side for my whole abdomen on that side starts aching. I'm worried if I've some serious condition. Please help.
