Hi. I've Had An Extreme Case Of Red Areas That

Hi. I've had an extreme case of red areas that turned into blisters, itching like crazy. I've been to my dr., steroid shot, slightly improved by the next day. Visited a clinic & it is possibly suspected to be scabies. Given a cream for that, to coat my body in, & antibiotic for a secondary infection I developed from all the scratching.
My question is this. Next morning, slightly improved, except neck & face & now new spots showing up above the elbow.

do you have an opinion, even though you can't see it? Sorry this is so long. 1st time using this Web site.
