I am experiencing something similar! I am having sharp pains near the site (to the left kind of underneath my rib). I am also exercising again after gaining 20lbs since my surgery 10 months ago. According to pictures it looks like I am feeling it at the wrap OR it could be the diaphragm. I was reading that exercising can strain it and cause those sharp pains. Hoping that's all it is! It's so stressful always worrying that something is going wrong
Hope your pains go away!
