I think I must have developed a metal allergy. I noticed since I restarted methotrexate (for rheumatoid arthritis) that I couldn't wear pierced earrings any more. Even though they are silver. The piercings were getting sore.

I have noticed that m skin is terribly thin on heel of right hand. Shiny and translucent.

Tonight I felt well enough to take down a guitar and tune it and played a couple of songs.   And now I have the most horrendous blister on the third finger of right hand (my picking hand) that feels like it has a shard of glass in it. all other fingers are ok. Usually the chording finger tips on left hand get sore from lack of callous. This is so different.

Has anyone heard of being allergic to guitar strings?
