taking topiramate, hydroxyzine, topical steroid cream

I work at 3 hospitals of the same branch on all floors dealing with all kinds of patients and coming in contact with all kinds of things. Recently, I developed itchy, umbilical blisters popping up all over my body. This is just one and one of the biggest and easier to photograph ones for me. Only about 10-15 now but I am continuing to develop at least 2 more each day now. They started on my neck at random and not really clustered too close together. No fever but some drainage, cough, and sore throat. I did scratch some before I got itch medication from my doctor and they burst and crusted up yellow stuff around them. My first thought was some mild form of chickenpox since I am vaccinated and had the virus as a child as well.

My doctor seemed perplexed by them too and admitted to not really knowing what they were. No new detergents, food, animals, travels, ect.. She said if I developed more after applying the steroid cream and taking the antihistamine medication then come back. Well that was Thursday and the hydroxyzine really made me sleep hard through the night and I guess they closed early Friday so I couldn't go back the next day when I woke up. I called urgent care to see if they would do PCR testing to see if they were chickenpox or shingles, but they directed me to the ER since they did not have the tests on hand to do so. I went to the ER and explained to them what was going on. The nurse was nice, but the PA brushed me off and laughed about it (which... fair... I am not dieing but I would like to make sure I am not passing on something that could kill the sickly babies and elderly patients I test). He gave me papers educating me on eczema and told me to call a dermatologist. 

I am kind of at a stand still with this and looking for further direction. Should I go back and ask for a second opinion? Is my hunch just plain wrong? 

Adult chickenpox or eczema?
