At night when I lie on my left side my left hip starts to ache and I get some pain in my groin area and my left foot starts to feel a little numb. Sitting on my butt and rolling to the left side causes pain in my left hip. I was wondering is this more of a hip issue or a possible prostrate problem. I am 64 fairly active with tennis,biking,golf,etc and in my 30's had 3 knee surgeries on my right knee. Seems to be worse in colder temperatures or stormy weather. As my pain worsens there is a need for more frequent urination especially at night. Advil gives some relief but still unable to lie on left side only a few moments.
