I've had nothing but back pain, I've never had any pain in my abdomen only in my back. I'm 2wks post op (2/9) and my back pain has gotten better. I couldn't stand or walk for more than and hr bc my back would start killing me! The pain would radiate across the middle of my back, just below my shoulder blades. Sometimes when I'm hungry, I feel that same pain in my back, it's weird. I hope you feel better soon!
