Hi, I too have this problem and signed on here once I did a google and found this thread.

36 yrs old
decent shape muscular build, regularly do resistance training

I recently started back running. I used to run years ago in my early 20's.

I was going good for about a month running about 2 miles, 9 min miles.

Then one day I get this pain as described above. The next day I could barley walk on the right leg. Sharp pain from hip joint down about 8".

I laid off running for a week. Bought new shoes. Ran again then next day same thing.

On top of that I think I have a pinched nerve in my neck and my pinky on left hand goes numb. Palm as well.

Is this what mid life is supposed to be like?
WTF?

Thanks
