Shingles like rash- test came back negative for shingles or herpes. What is this ?

I’ve been on antivirals for 5 weeks the bumps have been off and on. I just had the test results and they came back negative for shingles and herpes. not sure what to do they’re extremely painful.

Does anyone know ?

There have been instances of Covid causing rashes of all kinds. Have you been tested?
Viral rashes often just disappear as mysteriously as they evolved. Yours looks pretty painful…I hope it resolves soon. Have you been given antiviral cream to smooth into the rash, or just oral antivirals?
Have you changed your washing powder at all ? or new clothes? Changed your diet in any way? Taking a new supplement? It may be an allergy to something new. Try to wear 100% soft cotton and not polyester next to your skin…it may help
