I am a 53 year old, Caucasian woman. I have dry, scaly, red spots mainly on my arms and legs. I have been to a dermatologist and had a few places frozen. For years, they have been white but have turned red over the past year and a half? I was diagnosed with RA about 3 years ago and presently take methotrexate, Celebrex and Plaquenell. Could my medication be causing the redness? Is there any treatment to improve the appearance of my arms and legs?
