I had a band in Dec and gas pain for 12 days after surgery!!!! still get it whenever I eat too big a bite or dont chew enough but only for about 5 mins but its excruciating all around left shoulder and up my neck. Kind of saw it as a good sign I needed to slow down as was getting complacent. Since 2nd fill beg of March it's been much more constant even overnight or 1st thing in morning. Gotta wrap left arm around right shoulder like a straight jacket to get any relief. Have a massage booked today to see if there's a pocket of gas trapped somewhere but will def think about vitamin and water intake as prob not getting enough of either.
