Forget, as it was on my back i really couldnt see it. as it moved to new spots it changed shape. my research showed butterfly shape. it can last very long.
mine in the last 2 weeks have moved to my left arm. not a butterfly shape. it should be round, red, puffy and sometimes itch. yes it feels like sunburn.
what you will need to do is,when its a rash and puffy red the doctor can take a biopsy to check for lupus. i pray you dont have lupus as it is a very painfiul life long thing. you cant really look at the rash and say you have lupus, im told. now my heart doctor looked at the round red puffy rash and told me its lupus and gave me a allergist to get the biopsy. the blood work will be to check your other organs. there are only two meds to treat the symptoms.
im allergic to both of them. they make me drop to the floor and pass out. not sleep! get it checked.
