For the past 2 years, from about April - June, i randomly will start out with what looks like a mosquito bit, and then it gradually gets worse, actually a HUGE red itch rash either on my forearm, inner elbow, or top or arm. It also gets hot sometimes. I have been to dermatologist NUMEROUS times they have done about 6 biopsies. Chalk it up to contact dermatitis/ezcema. I have used clobetasol cream, prednisone etc.. could take weeks to go away. Its so embarrassing !. I have also been to an allergist specialist, yes i am allergic to ragweed and mold, so, is this rash coming out these times of the year because that stuff is airborne ? I live upstairs in an apartment. I DO NOT garden, nor go anywhere near grass. I am 57 and this started at 55. I hate it !... help....
