First time posting...and trying to calm myself down that I haven’t screwed this up already. I had my bypass 13 days ago, and have been feeling AMAZING. Today, though, I made two mistakes- I picked up the kitchenaid blender to put it away (waaay too heavy) and felt a little soreness. It went away after a while and then for dinner my family was having pizza. I had a very small portion of the ricotta cheese from a calzone, but there was a little mozzarella mixed in. I chewed super well but tummy didn’t like it. I threw up a little and have had a sore abdomen all evening. It’s been about 4 hours and my abdomen/stomach is still sore and tender to the left of my belly button, below the rib cage. I’ve googled every thing I can think of. Did I tear something? Is it leaking? Or is it common after a vomiting episode to still be sore hours later? I just feel disappointed in myself, and scared I’ve done real damage.
