I woke up early this morning with a severe skin burning sensation over my entire body. I had been laying on my side and the parts of my legs that were touching the mattress were bright red/purply with blotches. My arms and face were bright pink. I thought it was due to the niacin in my cholesterol pill so I took baby aspirin and went back to bed. When I got up I was pink from head to toe but the burning was gone. The pink stayed with me a few more hours then went away. I also had taken a muscle relaxer before I went to bed. Any ideas what caused this?
