Leg cramps/skin on fire

I woke up at 2:30 this morning with severe leg cramps in both legs. And I was up and around trying to walk them off, my left leg felt like my skin was on FIRE. That painful itchy feeling like the skin was insanely dry - so I asked my husband to put lotion on it for me and we noticed my leg was also red everywhere it itched and warm to the touch.

He put some lotion on it and it helped quite a bit, but also wtf??

Anyone have any experience with this??
