Karl,
Waaaay back in '95, '96, I was diagnosed with Sciatica. It only took them two years to figure out it wasn't Sciatica, but a herniated disk. Left leg would go numb, lower back pain, passed out once from it...et al. Ortho found nothing, what a waste of time. Finally I was sent to a Neuro....one MRI later, "Hello!" Micro discectomy on the L5 S1 and I was gold...until I was assigned to Ft. Carson, CO. Eh...screwed it up and now I have three bad discs.
Seriously though, speak to the Doc about a disc issue.

Odd tho, I sat and I was good...opened the discs some. Standing and walking KILLED me. Sciatica is inflammation in your butt cheek area around the nerve that goes through the "hip bone." Hmmmm....still worth the ask.
