I have a severe pain in my private area. it feels like something is trying to push out of my vagina. the pain makes my leg numb. what could that be?

Don't know: This can't be diagnosed with the information that is available. A history, physical examination & other studies may be needed to determine cause/causes.

It's hard to know: without a physical exam. Generally speaking, if your leg is numb, it is either due to a compromise in the blood going to your leg (for example a blood clot), or a sensory nerve being pinched causing the area affected by the nerve to go numb. I would recommend that you go to an ER or urgent care center today to determine the cause!
