For About 4 Days I've Had A Pressure In My

For about 4 days I've had a pressure in my stomach similar to a bladder infection. I feel like I have to go to the bathroom alot, but it doesn't hurt to urinate. I do however, feel like I have to have a bowel movement quite often as well and it appears there is mucus in the bowel movement. I have gas along with the bowel movement which send sharp pains in my stomach. I do have diverticulosis. Could this be a worsening of that?
