Bar rot..? Or citrus burn..? Solutions?!

Hey all! So I’ve been in the F&B industry for many many years and I have never experienced something quite like this.. I used to get my (finger)nails done regularly (Gel/dip specifically) until about 6+ months ago until my right ring finger tip became extremely sensitive (only that one which I find odd..) so I stopped. I keep my nails short, but I haven’t been able to find any cuticle or nail products to help fix this!! I work at a bar outside (in the heat, sun, etc..) so it isn’t practical to wear a glove at all times. I have noticed that when I don’t work for 4+days in a row, the pain is gone, but my finger tip looks funky... this is after a 10 hour shift on a Friday (it doesn’t hurt.. yet..) after having 3 days off. Any suggestions?
