Yes, warts do seem to be common for crohn's sufferers. My husband gets them all the time. Most of the time, he freezes them off himself. However, he got a plantar wart on his foot that just wouldn't go away no matter how man times he blasted it, or put acid on it. His dermatologist referred him to a podiatrist who worked on it for a few months, and it still wouldn't go away. Then he tried pulse dye laser treatment, and now after over 10 months of treatment, they _think_ they've finally gotten rid of it. He's keeping his fingers crossed hoping that that's the end of that.
One of the reasons we bought equipment for a home gym, is because gyms are a big source of warts - lots of equipment is not wiped down, the locker room floors etc. Since he started working out at home, he doesn't get nearly as many warts as he used to - it's been a major improvement for sure.
