Thank you for your question, and I am sorry to hear about your symptoms. There are obviously a number of different possible explanations that you are having, but it is somewhat difficult to think of one particular reason or explanation that would exactly describe the migrating symptoms that you have mentioned. Sexually transmitted infections are obviously a risk among those who have unprotected sex, and there are a number of these that are quite common. Depending on the number of partners that you have had in the past, it could be more or less likely that you have obtained some of the more common sexually transmitted viruses that are quite widespread. Your OB is a good place to start, as he or she will be able to do both an examination as well as some testing if they feel that it is appropriate. There are things other than infections that could be causing these symptoms as well, and your doctor
will be able to discuss some of these with you. It could also be that some of the symptoms that you are experiencing are in part due to your experience with the person and the event. Please speak with your doctor more about this question.
