Hi I Am A 58 Year Old Male. I Weigh

Hi I am a 58 year old male. I weigh 210lbs. I had a negative colonoscopy in 2016. I've been having pain and swelling in my upper abdomen area for about a month now. Bowl movements does not give me relief. Some times it feels better after I eat. But it doesn't last very long . My stomach feels like one of those big rubber balls. Not much gas pains.
