I have 24 week negative Hepatitis panel yet I am still itchy all over, burning mouth with burning rash on lip that isn’t herpes after confirmation from GP and dermatologist. Negative HIV 24 week test. Negative oral gonnorhea and chlamydia. Very brief Cunnilingus and analingus exposure. Thoughts what is causing all of this? I have tested well outside window periods for all stds including Hep B and Hep C. Beyond frustrating.
