My fingers, only on my left hand (specifically first and third finger), experience terrible eczema a few hours after I play my bass guitar. It gets so bad that I wake up having the worst itchy sensation I've ever experienced. I thought I had it figured all out. I assumed it was the nickel in the strings, and that I had an allergy. So, I switched to a set of DR stainless steel strings. That seemed to work. Then I bought a precision bass that I wanted to have flatwounds on, so I bought a set of Fender 9050's, stainless steel flats. That did not work. I need someone who has experienced this same thing to help me out. Are there strings out there that you are for sure have no effect on your allergy? I think I might've read something about D'Addario Chromes doing the trick, but I need a second opinion. Also, if anyone has anyone has knowledge about how humidity affects your strings, let me know. I think the fact that my band practices in a garage and I leave my bass out on it's stand all the time might have something to do with it. I've played on Fender 7350's, stainless roundwounds, and they seemed not to bother me, until now. I'm thinking the environment of my bass is suspect. I'm really trying to get to the bottom of this so I don't waste hundreds of dollars on strings that irritate me. Thanks for your help. It's a major bummer that I'm allergic to something I love so much.
