Very itchy bumps on arms, face, ears, and neck. was told it was sepsis first then an allergic reaction, then shingles. still no relief?

Itchy skin: Needs a doctor assessment for specific diagnosis but here is some general information about possible causes: http://www.dermnetnz.org/topics/differential-diagnosis-of-very-itchy-skin/

Can't tell: but, doesn't sound like shingles, nor sepsis, you still need to examined for a definitive diagnosis, hence right management, kindly see a dermatologist, or seek a second opinion, it's your right, good luck
