when it turned cold a week ago I delevpoled bumps on my right arm it was three bumps at first, then it was a cluster of bumps two days later. Then I took a shower and scubed really hard, and now their all over me. I can remember when I first moved here back in 1998, I was in the back yard and I saw the same thing, first on my ear, then on my arm and then on my private part It lasted for a week then it went away. The last winter I developped a rash on my right leg, and now it s a little bigger, could it be the cold weather with the pollon and stuff blowing in the wind
