it would be impossible to predict the outcome of a skin eruption since every person is different when it comes to healing times. additionally it appears that you have not been definitively diagnosed so seeing a dermatologist at this point would be prudent. a "rash" is a very very vague diagnosis. there are thousands of causes so after six weeks of treatment failure i think you need to see a specialist.
how long does a rash last. had a rash all around my mouth for 6 weeks ( just like a go-tee) and nothing is helping hydroclorasone eucerine etc. now it's under one eye and eyelid. the doctor told me it was a rash . it doesn't really itch but it gets quite red and lightens up from time to time. another doc said infection bacteria or fungal. tried anti baceria and fungal cremes to no avail. heeeeeeeeelp!
