About 3 months ago, I performed oral sex on a woman briefly. About 2 weeks afterward, I began experiencing some nausea and diarrhea. Soon after that, I began experiencing mild random leg pains and a sore throat. It went on like for a week or so, then I felt ok. Then I had sneezing, runny nose a month later and now (3 months later) I am having nausea, leg pains, sore throat again, as well as some tiredness or fatigue. I had a blood test for hepatitis 4 weeks after exposure which was negative. How accurate is a test at 4 weeks? How risky was this behavior? Does this sound like hepatitis? What should I do going forward?
