I have moderate pelvic pain for 3 days?

Pelvic pain: The human body is a sophisticated 'machine". It is wired with nerve pathways that send signals to the rest of the body giving an ongoing account of its' operational status. Pain is one of the responses that clearly state to the "recipient" (you) that something is definitely wrong in its function. See a GYN MD and get "plugged in" to a "diagnostic computer"( exam) to keep your "machine" operating.
