Anyone have sciatica?

[Tenor CS]

Hey guys, although my health issues of last year have finally healed, I am now dealing with another issue.

My chiropractor is pretty sure I have a pinched nerve in my low back. I have an MRI coming up soon, but right now I am in almost constant pain.

If I am on my feet for longer than 5 minutes, the front of my thighs start this terrible burning sensation. It's alleviated almost immediately if I change positions, but for about 2 weeks, my thighs have had this weird tingly sensation that's especially bothersome if my thighs experience light pressure, like someone running their hand over them.

Any of you guys (especially my 300 lb+ BOTL) have this problem? Any tips, hints, tricks? How did you find relief? I'm hoping that if I have a bulging disk, I can maybe get some cortisone or similar shots to reduce the swelling and relieve the pain.

Any advice is appreciated. My MRI is still over a week away, and I'm friggin miserable right now!
