rosacea
"I'm 53 and have very bad rosacea. My derm put me on doxycycline 100mg x2 a day. It cleared up my face great. She reduced the dosage to 50mg x2 a day  everything was great until I started having joint problems. I never had that first joint prob before. I went off med for a while and rosacea came back with a vengeance. My doc told me to try med again and if joint prob returned she would take me off of med for good. I did this and all of my joints got very bad so I stopped taking drug. It's been 6 months and my joints are still recovering. The med package said 1 in 6 will develop joint problems. I'm one of them. Now srosacea is bad and I am bumming heavily."
