question: I had hernia surgery a little over 2 weeks ago. I have been fine. 2 days ago I got into the pool with my 6 year old and got a rash on back, neck, arms. Very itchy. I havent taken the pain meds in over a week. I feel feverish but no fever. I do have pimples on my right leg. I dont know if the rash was because of the sun or maybe something else
