HI I have gone through your mail, as you said that you have enlarge right tonsil for last one year and you notice this after unprotected anal intercourse with a guy and now you are worried for HIV
infection. After listening your story I would like to say that enlargement of tonsil on one side only occurs in - (1) Tonsillar cyst
(2) Tonsilolith (3) Neoplasm
of tonsil (4) Quincy . So you should contact an E.N.T.specialist for clinical examination to make the diagnosis and than treatment. As for as HIV infection is concern you should go your blood examination to clear the suspition. Thanks.
