About a month ago, I noticed that one night my stomach was swollen in a very concentrated area, about a quarter diameter in the lower left right at the end of the colon, and it was hard. As soon as I passed gas it resolved. It's been doing this on and off, I get very bloated and the spot bubbles up like there is trapped gas and then when I release gas it gets better. Is this normal bloating symptoms?? This is new for me, I've only dealt with perianal things for the most part. I am hoping this is just inflammation that will resolve over time and not a budding obstruction I will need to address with surgery. Help!?
