Oh I know how you feel!!! Mine usually isn't in my back, but it has been in the past...it's usually right under the left side of my ribcage...and YIKES!!! Last week it happened at work, and I had to go curl up in our lunch room for an hour and a half and massage the spot before I could get any relief. Relief that came in the form of a big, large, loud, smelly toot. But MAN did it ever feel good!
It actually happens quite often...but for me I can pretty much figure out exactly what I ate that gives me that type of gas. My doc said to sip a cup of hot water with lemon, it helps move the gas down. Or you could try laying on the ground and moving your legs in a bicycle kind of motion...although for me, that would have been too painful.
Hopefully that's all it is in your case!
