Recently i have these painful spasms/twitching at the lower right side of my back, probably somewhere near the lower ribcage, it happens a few times per day and it goes away for a very brief short while, it feels likes something is pinching, or at worst stabbing, i can ignore it most of the time but recently the frequency is slightly higher. Hope its not gallstones, i am really afraid to undergo surgery. Do u guys hv any idea what this is, thanks a lot...
