what do you do that could cause it? working out? work?

You have a form of sciatica. You probably hurt your back or tweaked it at one time and now it's causing you problems. What happens is that the muscles in your core (hips, thighs, buttocks, lower back) spasm and get knotted. When this happens they pull your pelvis and spine out of alignment. What I did to stop my problems is to start doing inversion therapy or hang upside down with gravity boots. As you invert the muscles of your abs are stretched and the knots are broken up. As this happens they release their grip on the muscles in your hips and thighs. As they loosen they will release their grip on the muscles in your lower back. As this happens they in turn release their grip on your pelvis and lower spine and allow it to go back into alignment naturally with gravity. When your spine and pelvis are out of alignment it effects the sciatic nerve and that's what's causing your pain. I guarantee if you try inversion therapy within a week or so your pain will be gone. Here's a good site to read about what I'm talking about. Hope this helps. GOOGLE: sciatica online health mart :to read more info on this subject and to see how to treat sciatica.

Sounds like a muscle spasm. Have you tried a muscle relaxer? I use Soma which works really well. You can actually order it online at www.ordersomaovernight.com where they use U.S. licensed doctors and pharmacies and the same FDA approved meds as your local pharmacy. You don't need insurance or a prior prescription to order. Just fill out a short form and you'll get your meds next day. My doctor referred me here and I've been ording for about six months now and the Soma has worked wonders.

I had the same thing to happen to me 4 years ago. Went to the doc. I had bulged a disc in L4-5. Now I've got pain in my hip and in my leg that only hurts to my knee. Mine is on the right side down. My pain comes and goes down my leg. In the lower back though it hurts all the time. It sounds like you have a disc and nerve issue going on. That is from my experience.. I hope this helped you. If it gets no better. Go to the doctor. My doc. want do no surgery until I'm hurting down my leg is all the time. But my back will still hurt. He did say there is nothing he can do for it right now..
