I'm a 28yr old female very healthy. 145 pounds 5 foot 1
I have a rash that Started on arms 3wks ago moved to legs rash on legs gone but now its all over my back neck and around the stomach. Also some on one breast.
I've taken allergy medicine seems to relieve symptoms should I continue when should I go to doctor.
What worries me is it seems to go away than come back. It will nearly disappear after a few days than come back
