Scabies? or Spider bites?

I have clusters of red blotches that are raised and firm.  The surface of the 1-2cm blotches have become bubbly.  Tiny bubbles like poison ivy.  It's not very itchy, but does feel uncomfortable, bordering on itchy.  More of burning sensation.


This discussion is related to very itchy red blotchy rash on torso, legs arms, back, and neck.
