Hi abrniidgrl and welcome
I am so sorry to hear of your troubles....it really sucks. I gave a few suggestions to some other sciatic sufferers (since nothing is getting done right now why not try out some things to give you some temporary relief?).
I'd tell you the thread if I could remember which one I posted it on....hehe (sorry). So I'll do my best to remember them all.
(1) ICE - ICE - ICE. Ice is your friend. It keeps the inflamation down so that your sciatic nerve can "breath a little". Ice for 20 min. every hour (so you ice for 20 min. wait an hour and then 20 min. wait an hour, etc.). Use the ice gel paks, they are the best (it's worth the few bucks investment). Never put ice packs directly on skin...I like pillow cases to cover my packs if my clothes aren't enough barrier.
(2) Get as much sleep as possible. I know the pain keeps you from sleeping, but Valerian Root is a good sleep enhancer. Our body and (especially) our nerves can only repair themselves when your body is static or dormant. Resting doesn't count....but cat naps do. You must be in the deeper stages of sleep. When you aren't moving and your auto-immune system has only to deal with the "here & now", your healing powers are at their peak. Otherwise, they can't deal with that stuff when being constantly bombarded with our dirty environment (all the way to the air we breath).
(3) MYOCALM. I found that to be the best herbal treatment for sciatica on the market. It is really hard to find and you may be lucky enough to find something by going to a search engine in typing in the name. It stops that "electric" feeling running through your legs, it stops the twitches (or at least minimizes them) and it takes the BITE out of the sciatic shocks (you all who have experienced them know exactly what I'm talking about).
(4) Pelvic Tilts. Do them correctly and you will have a new best friend (right next to your ice pack). Lay horizontally with knees up and feet flat on the floor. Without moving any body parts intentionally.....visualize yourself bringing your bellybutton down to touch your spine. Doing 3 sets of 6 will hopefully give your sciatic enough space to function a little better (so less or no more sciatic shocks as well as less twitching). If anything causes a sharp pain...stop immediately. This movement is barely visible to someone watching...so that would be your cue to move less and "imagine" more. Put your hands on your hips and you will feel the tiny movement that will hopefully give you some relief from your daily sciatica.
hmmmm.....I am thinking there is a 5. Darn. Can't think of it right now. But these should help a little. BTW....I took Myocalm when I was also taking vicodin or percocet, soma, an anti-inflammatory, a laxative and zantac. No adverse affects.
Take care and good luck.
