Re: Unknown Illness causing Fever followed by Mouth and Genital Ulcers
A description of the lesions (size, how they progressed, itching?, etc) would be helpful, but this could have been a primary herpes infection. I would think about any possible exposure to the herpes virus. If it was herpes, it will likely recur at some point without the fever and much fewer lesions. If it does, it should be cultured or antibody levels checked. Antibody levels can be done now as part of the convalescent stage. There are other disorders that can cause fever, mouth and genital ulcers that fall into the rheumatological category, like reactive arthritis (Reiter's syndrome) and Behcet's (rare). If your illness included marked joint pains, one of rheum disorders is more likely.
