beautifullysleeved2019.....As GreenTealael said it could be a number of things, HYDRATE, but most importantly FOLLOW YOUR SURGEON ORDERS. For me Stage 1: Sugar Free Liquids only, no protein.Are you still using your I/S device? I had pain in my upper back/shoulder but when I use my I/S device that subsides. When I have pain around my incisions I take my liquid pain medicine I was prescribed.Walking also helps. I know everybody is different, just sharing!
