Hi, and thanks for your question.
These symptoms could be related to any number of things ranging from viral or bacterial infections all the way to stress, fatigue and anxiety. However, they are not symptoms of any STI. If you are concerned about an STI from the encounter 4 months ago or any other sexual encounter we would recommend seeing a care provider for testing.
