It may sound odd, but I have lived by bellly rubs (flat palm beginning on right (ascending colon) side, up over belly button and around to left and down and around, back to right side). This is massaging the digestive system and seems to alleviate the discomfort. It will initially feel as hard as a rock sometimes (when beginning) and by the time five minutes is up, I feel a relief and the tummy begins to get softer. It warms up the belly and gets circulation going.
I also do Bikram "Wind Removing Pose" (google it and follow it exactly as it explains), twice in a row, sometimes twice a day. That seems to also help.
I would also eliminate any carbonated beverages, if you drink any. That carbonation can increase bloating. I am experiencing the same thing now, after having a bad reaction to an antibiotic. I am basically living on soups and water, as I rest the stomach. I am also taking probiotics and yogurt.
Hope something helps!
