You have multiple negative tests, thus conclusively you do not
have HIV. I do not
doubt that you have a sore throat
but to expect it to be due to HIV with multiple negative tests is unrealistic. Furthermore, had you had the ARS, the sore throat, accompanied by other symptoms would have come and gone by now. My advice is to stop worrying about HIV an see a health care provider to get their assistance in sorting this out. If a GP is not helpful ask to see and ear, nose and throat doctor.
