I just recently started exercising again after a year with perianal fistulas. I still have them, but finally have the energy and stamina to move. I've noticed that once I cross the 40-50 min mark on my walks/hikes the area around the fistulas gets super sore and raw. So bad that when I took a shower the water stung. Usually, they don't hurt and drain minimally (unless of course they're flaring from me eating bad food). Does anyone have any advice on how to stop or prevent this? I do use a gauze down there at all times but it isn't helping at all. I really need to get healthier but this is driving me nuts.
