Welcome to the STD forum.
This doesn't sound like any of the usual STDs. Oral/throat herpes causes very severe throat pain that clears up within a couple of weeks; herpes would not cause the sort of prolonged symptoms you describe. The lack of response to antibiotics further supports the idea that this is a viral infection, allergic problem -- almost certainly not a bacterial infection. Your thought about mononucleosis is reasonable; I would have suggested it as a possibility before I saw your own comment tabout it. This is something to discuss with your doctor. And I also agree that HIV is a possibility; it would be reasonable for you to be tested for it, if not yet done. (Do you know your partner's HIV status? Of course common sense says that you should have asked before becoming involved.)
Sorry I can't be more helpful. I'll be interested to learn what the eventual diagnosis is. Good luck--

Main thing.. (and this is coming from a person who is a hypochodriac) DONT google your symptoms and read and read on diseases. It'll make you seriously crazy and your mind is a POWERFUL organ that can make you believe that you ARE experiencing certain symptoms. So do yourself that favor.. and dont look up symptoms because its counter-productive to your well being. Remember, our minds can help OR hinder us from feeling and gettin better.
Most importantly.. i know this is tuff. Its frightening and painful.. but try try try to keep your head up. Think positively and remember.. you arent the first with these symptoms and you Definately wont be the last ; ) all the best..
Users need to interpret each reply, whether by me or Dr. Hook, strictly in the context of the exact questions asked. A certain amount of generalization is OK, but whenever there seems to be a potential discrepancy in our opinions or advice, it is important to look very carefully at both discussions and be alert to differences in context.
This reply is not intended to imply an ongoing discussion. I won't have any other comments about this.
