So I'm having some weird reaction on my hands i think. I lifted my jeep about a month ago, and for the most part did it w/o gloves. I usually wear them for everything, but on the lift i started w/o them and just never got around to putting them on. at some point i did put them on and ended up getting grease/oil/dirt inside, but didn't care much. After finishing the work, the next day my hands were really red and burning. It hurt to touch things, and my hands felt swollen. all of this was on the palm side of my hand, and a little around the knuckles on top. the gloves had been sitting in the garage until yesterday when i washed them and used them to do a side job that i lined up for some extra cash. I got some new gloves but didn't want to use em so i used the old Mechanix ones. So now today i got the same reaction on my hands. Just wondering if anyone has ever experienced something like this from any kind of grease or oil from the car. While doing the lift, i also did the diffs with regular GL-5, not synthetic. I think i did get some of the old diff fluid on my hands, maybe thats it? other than that the only things that got on my hands was lithium grease from the zerks, and dirt fromt eh undercarriage. any ideas what this may be?
