I usually do an hour or so on the stationary bike per day. However, I have developed a small perianal fistula and am thinking that staying off the bike may be a good idea, at least until I can get into my colorectal surgeon and see what she says. Just for some background info, the fistula is not inflamed and is causing very minimal pain, but is draining. Anyone have some advice on what forms of exercise I can do until the fistula heals up?
