I had gastric bypass in 2003. Within the last 5 years, I get a pain in the upper center of my stomach. It comes on when taking 1/4 of a pain med such as Percocet or oxycodone, some allergy/cold meds OTC, and alcohol. (Not in combination, I rarely drink and only take any pain meds for a surgery and only a couple doses). I need to have a lot of skin removed and I am ready to consult with a plastic surgeon but am afraid that I might need pain meds that will cause this pain I get. I also sometimes get a strange cramping on my right side when I lay on that side. I literally have to hold my stomach to turn back over or the pain is intense. Wondering what it could be and if these symptoms are related. Thanks so much!
