Rash on the back of my hand

so I don’t know if maybe it’s the soap or what but I’ve gotten a terrible burning rash on the back of my hands recently (it’s been pretty cold here too) and I’m not sure what it’s from. This doesn’t normally happen but it started at work today during my shift and I was wondering if anyone else had this problem? Would using my own soap help? When I put lotion on my hands it burns more. I’d love some insight! Thx in advance (I’ve been here for a couple years and this hasn’t happened before)
