Hi all, I have a quick question. I'm a 24 yo male and I had a PPD test done the other week because I'm going to med school next year and I need it for my paperwork. Anyway besides that, I went in after 72 hours (got it done on Friday and they weren't open on the weekends) and it was slightly red, maybe about 7mm in diameter, no induration and it wasn't raised. They MD said the test was negative. The next day I noticed that the the area was slightly redder than before, and measuring the size of the circle, it was 10mm in diameter. I have been going tanning this week and last week since I am going to vacation in a few days, so I'm not sure if it caused the area to become more red. It's been a week now since I've had the PPD test, and there is still a 10mm red circle. It doesn't itch and isn't hard. I'm not sure if it's an allergic reaction or maybe some kind of subdermal infection. I have been putting hydrocortisone 1% cream for the past few days, but no change. It doesn't bother me but I don't want this to stay there. I'll be out of the country from this Sunday until right before Christmas, so I won't have a chance to go to the doctors until probably after new years. Hopefully it isn't anything major.
