I recently had a visit to er,I had been having lot of gas pain and it traveled to the back. The pain was under left rib! moved to back,middle of stomach! Found out I had 1 gaul stone,of sustantial size,and kidney stones,which I've had before! Kidney stones usually come out with lots of water.Dr. in ER gave me nexium,it helps,but get discomfort on and off. Today I have waist pain in back,but I may have strained my back from lifting! Unless it's from kidney stones or gaul stone. But ER doc. was surprised,I had pain on oposite side of gaulbladder! I told her my mom had gaulbladder out,they did ultra sound,and found lots of gas,and gaulstone,they said it looked like it was going down the track,and went back up. They told me see gastrologist,but no ins.! Any suggestions?
