The last 2-3 weeks, I have feeling of pressure or fullness on my right side, mid to lower abdominal area, that is tender to touch if I press on the area. Had a colonoscopy 3 months ago, with 2 polyps removed (from ascending colon) and some soreness afterwards, but that resolved with a week or two. The fullness feeling is exaggerated when I am bicycling - on the upstroke. 51 year old male.
