I Developed A Rash On My Hands About A Month

I developed a rash on my hands about a month and a half ago. They started out what I thought were itchy small pimples. When popped only clear liquid came out. After itching them almost raw, i had a red painful welt as well as peeling skin. I have been told by my fam doc he doesn't know what it is so he put me on a steriod and a steroidal cream. It seems to be spreading more and are now on my fingers and even on the top of my hand on one of my fingers. I have pics if it would help. I've been told eczema, shingles, lupus, & even a sude effect to my hypothyroidism or fibro. I see a dermatologist in June. I cannot live that long not knowing!
