5 days ago, I had pain in my left side groin area. It has slowley gotten worse and has traveled down my thigh, and today past my knee, just above my ankle. When I get up to walk, the throbbing pain down my entire leg causes me to stop & lift my leg q couple of steps. That takes the edge off, but still throbs. When laying down, the pain continues in my groin & thigh area, making it difficult to sleep.
