Every few weeks i have pretty bad bloating and a very painful hard stomach thats only relived by burping or excessive yawning. i also get pain in my left breast, and it affects my breathing, and it hurts. what tests can i ask for?

If you're making yourself burp you'll only be swallowing more air & collecting more gas. Drinking hot water helps break down gas & enables it to be passed down the intestinal tract & out the rectum which is best. Applying heat to the abdomen does the same. In addition to avoiding gassy foods& beverages, take simethicone to prevent gas build up. Get tested for lactose intolerance or gluten sensit
