I hope you do not have MS or Lupus.
The pain that I have experienced so far starts at my lower back and travels down to my hip and then to the front of my thigh, ending where the numbness begins.
I had had hip pain previously, but that was due to my body being out of balance. I used forearm crutches for over 2 years which allowed my time to "re-balance". The pain was different than the nerve pain. The nerve pain was unbearable!
I wish you the best.
