A heat rash in winter?

Today, I realized that my lower, inner thighs (closer to my knees) was burning. I looked and it looks like heat rash. However, the temperatures here where I live have been around 15 degrees and below last week or so. By So I do not understand how there can be a heat rash. I have bad dry skin at the moment and I do not think my skin has been handling the cold weather very well. I have skin very sensitive. I've also been in and out of cold weather throughout the day shopping …. Also I have a small coin-shaped spot on the back of my arm looks like a ring worm (BUT NOT ITCH). It feels as if the dry cycle, I did some internet research and I think it could be Exzema Coin, taking into account I have in my legs …. exzema My skin is all jacked … lol ….. Any input would be great!

It may be winter itch. I know there is itching, winter itch, but not always itch. Try E45 relief
