Crural Neuropathy

It has been suggested I have this, not enough blood flow. I have constant pelvic gut pain that can make my groin and thigh uncomfortable. Even my BM's can be very sluggish. It seems more and more that I have a nerve problem and just to what extent I do not know. I have been relying on NEURONTIN nightly, tired of that. Someone told me I should investigate stem cell therapy. So, I would value input if the crural nerve can affect the gut, groin, thigh, and what might be done to alleviate pain that is everyday.
