Hi, I recently had two dislocations of my artificial hip. The first time I did great with no symptoms but didn t pay attn to precautions (I m 44 and very active). The last dislocation was 8/24. I have felt fine since then--no pain. Today was the first day I tried to exercise on my elliptical. After about five minutes, my foot became numb and cool. I am praying this will get better with time? It isn t numb just with walking, only exercise. Will this go away with time? Thank you!
