Dermatologist: DocPhilMD, Doctor replied 8 months ago

Yes, this is a sun rash.

It should go away on its own in the next couple days

If it doesn't you will need topical or oral antibiotics like keflex.

That will take care of it

I feel better already! Thank you.

ElanorTracy, CA

Thank you to the Physician who answered my question today. The answer was far more informative than what I got from the Physicians I saw in person for my problem.

You have been more help than you know. I seriously don't know what my sisters situation would be today if you had not gone above and beyond just answering my questions.
