Yoga and Sciatica

I dunno but Ill ask BOOBOO.

The ranger wouldn't like that, Yogi!

I'm given to understand that sciatica pain is absolutely excruciating, although I personally have never had it. I understand that it's like emergency room painful. It is always a consequence of another problem such as back pain. I have heard that physical therapy is useful for chronic back pain, although that, of course, is under the supervision of medical professionals. I'm not a medical person in any way, though, just repeating what I hear.
