Buy a new football. Sorry.
My mother was recently told that she has air in her bladder. Her doctor said that there are two ways that air can get into the bladder. One is when a catheter is inserted air can go in with it. The other is a fistula between the colon and bladder that allows air to enter from the colon into the bladder. I have since seen an article that says that bladder infections can sometimes cause gas (air) to build up in the bladder. Hope this helps!
