I got a sudden rash behind my neck/upper back area 2 days ago. itches all over but the welts are only on neck/back/head and behind my ears. the little welts look similar to chickenpox and are puss filled. possible covid? my daughter was exposed?

Doubt it: The limited location & cited appearance suggest a contact dermatitis reaction to some agent. This could be a shampoo/soap or other material that passed over the area. Keep it clean & it should heal. It does not sound like covid.

COVID fears: This description does not sound suspicious for COVID 19. COVID 19 sx’s: dry cough, shortness of breath, chest tightness, nasal congestion, sneezing, fever, headache, sore throat, feeling tired, loss of sense of taste/smell, decreased appetite, nausea, diarrhea, vomiting, chills & muscle aches.

Exam advised: If the eruption was only on.one side of your body, shingles would be highly suspected, but would not appear behind both ears. Another type of herpes outbreak would be a possibility. Since treatment is available for these infections, I strongly recommend being examined by a physician or dermatologist for diagnosis and treatment.
