psoriasis
"I have had psoriasis for over 40 years, and although it's just on my elbows and legs, I have tried all the usual remedies (topicals, light therapy, etc.).  I tried methotrexate this spring and in a matter of weeks, my psoriasis began to clear up. My doctor has me go for blood-work every month or so to make sure the methotrexate isn't affecting my liver.  We have decided to back off of the methotrexate during the winter in order to give my body a break.  But, I'll be anxious to begin it again come spring!"
