I had a double mastectomy with reconstruction (750CC silicone implants) done on 08/11. They always feel kind of heavy and I have to wear a sports bra or a regular bra. The last two months I get sharp pains on my right towards the arm pit are and the middle of my cleavage. The left implant towards the top. My PC gave valiums to take when my muscles are tight and lately I’ve been taking them just to be able to feel comfortable so I can fall asleep. Any suggestions? Do I need to worry?
