I wear a sleeve for mild lymphedema. I just started getting a warm red rash on my upper arm, and spotting blotches on lower inside arm. The rash is not raised. It reminds me of rashes I have had in the past if I would walk for a little while or even riding a golf cart from the vibration. When I walked, I got it on the insides of my legs, and I would have to scratch. On the cart, it would do the same to my back. The difference between now and then, I use to get sick in the stomach at the same time I got the rash. Usually it would disappear in a few mins. I haven t been wearing my sleeve all day during the holidays. My upper arm has one big solid blotch.
