On 11 of march I had protected sex with a sex worker, Condom at the end was fine. I didn't do anything risky. After two weeks I had my blood tested. HIV, Hepatits Negative. Then I had fungal infection on sides. I wen to doctor and It disappeared after 10 days. Then I had my mouth burned with hot tea and ulcers started to develop in on my tongue. After 6 weeks I had my blood tested again. Negative.Also for two weeks I had pain in back of my knees. Then the last symptoms that I have is again tongue ulcer with no reason, pain in my neck very close to lympha nodes also back of my neck. Doctor told me my lymphs in the neck are swollen and when I push them hard they ache. also in groin I feel some pain but when I push them , I don't feel pain. I ve been under sever endless stress for the last two month, and this time badly scared to test my blood. The thing which scares me the most is thos swollen lymphs and ulcers. can you tell me if I need another blood test or am fine with two tests.
