I am having red rashes on my arms since last 1 week. i started getting burning sensation since last 2 days and also rashes increased. they look like ring worm but am not sure if they can be heat rash or something else. wanted to know the dr's opinion?

Have to see it: Rashes are best diagnosed by having a healthcare professional look at it. Recommend that you see your provider or setup a telehealth consult so that you can be treated with the appropriate medication if needed. Ringworm does have a circular raised appearance, it can itch or burn and spreads easily. There is an antifungal cream that you can use, sometimes takes weeks for it to go away.
