I had this happen to me just minutes ago. I was cleaning the stove and suddenly my fingers on left hand started burning. Immediately after the burning sensation, white paint like substance appeared on the same fingers. I tried washing it off, but it only made it spread. I freaked out and immediately got on the internet to see if this was related to fiberglass exposure. I didn't know what else it could be. It seems to be going away on its own and no longer burning as much.
Same thing just happened to me. This is the second time. Both times it goes away on its own. I feel a tingling or pricking sensation just before I notice it. It's under the skin an followes the pattern of the fingerprint . Looks like paint but comes from out of nowhere and does not wash off. I took some pictures. It's weird. It just goes away on its own . A friend had the same thing happen to her. Maybe it's part of this DNA upgrade we are supposed to be getting ;)
I think you need to consult with the good skin doctor. May be it is some kind of food allergy.
This just happened to me and I found out that it was Food Grade Hydrogen Peroxide I had in my freezer! It had tipped over and it was on some of the bags of food in my freezer. I had no idea where this was coming from because I didn't notice it right away the other times. so thankful my mom had mentioned that had happened to her and sure enough when I went to touch it in freezer my hands started to burn and turn white!
I had the same thing happen after moving and cleaning an office. Based on the pattern of your reports, it seems it's something that occurs when in contact with cleaning products. My guess is that you each were using the cleaning wipes (not the kind for face and hand) from maybe Lysol or something. Thats happened to me twice including today but still cant find an answer as to what it is. Weirdly though, I panicked and taped all my fingers so I dont touch my face and within 30mins, vapor somehow built up under the tape and when I removed them, my fingers looked good as new, like it NEVER happened. I quickly washed my hands n now am paranoid but the look super clean again. Anyone find out what it is and if its benign or not, please post here. Thank you.
Three of us had this this morning and after reading your post I see that it was the food grade hydrogen peroxide I had in the fridge which spilled near our cheese and everyone who reached for cheese got this white stuff on them I noticed mine was really itchy. It did disappear fairly quickly in a few hours.
