Hi, sorry you are feeling sick. Have you had a throat culture? Are your lymph nodes swollen? Any fever? It could be a number of things. Are you very fatigued? It could get mononucleosis, or a Epstein Barr Virus. Those don't respond to antibiotics. Have you had a complete blood count, and thyroid test for TSH? Also, if they don't think it is viral you could get an endoscopy. Let me know what other tests they have done . I am the community leader for the infectious disease site. You can also post there.
