After severall years of travelling, on my most recent vacation I ended up getting a pretty bad sunburn which ended up being sun poisioning and left me with swelling of the face, i got a cortizone shot and took some prednisone and i was fine, the other day I was outside for just a short period of time and I woke up with 2 odd looking red spots the size of a dime one on my forehead the other on my neck the one on my neck was very itchy the one on my forehead was not, I'm wondering if this is a reaction to the sun, as I've been putting cortizone cream on and nothing is happening...or could this be something more serious?
