It was bad but not oozing pizza face bad like they show in the before and after brochure. I usually had 4 or 5 cysts going at a time, and those suckers hurt like hell. I'd tried all the other stuff, and it was only getting worse.
Yes, my joints did ache, but I think this was only at the beginning. Maybe it went away or I got used to it, because I don't remember it being a problem. Another annoying side effect at first was I felt really itchy all over my body. Thankfully that only lasted a few days.
The worst part of the whole treatment, other than the monthly blood tests, was having the corners of my mouth crack and getting nosebleeds from the extreme skin dryness. A & D Ointment helped in both places. I wasn't into drinking much water back then like I am now, so maybe increasing your water intake would help too.
