Hi i am 17 years old and for the last 2 weeks i have begun to feel a tingling/ bubbling sensation that runs from my perineum to the left side and back of my left testicle and into my left groin. There is no pain involved and i have no idea where the sensation came from. The feeling seems to only occur when i am sitting or lying down, otherwise i feel very normal. If any one has experienced the same feeling or knows how to treat i would be very thankful.
