Hi Cassie, Don’t panic! I am exactly the same! Had my op on 10th was in pain but thought that it was easing slightly then and on Sunday/Monday it got really back but mainly in my left boob. Was getting this intense burning feeling and the muscle kept contracting which was so bloody painful. I started to really worry that something was wrong. Rang the nurse who told me that it was completely normal, that the muscle is used to being flat on the chest wall but now it has an implant behind it so its stretched and trying to contract back flat. Once it relaxes and stretches it will be fine. I couldn’t stand the pain though as it was really getting me down and I’m back to work today so I went to my GP and they prescribed some more cocodamol, so I am back to being drugged up but at least im not hurting anymore. Try not to worry, everybody healed at different rates xxx
