Hi, i am a little concerned about a sudden appearance of a darkened/reddish skin rash which doesn’t seem to have faded. It looks like a light burn mark but haven’t been in the sun at all and always wear protection. It’s about a the size of a thumb print above my right breast to the left of by my bra strap- it’s not raised or itchy but would like an opinion - should I send you an image to see if a doctors appointment is required ??
