If you've tried the first exercise (the back settle) you'll most likely have felt some relief in that position.
Now what we want to do is to build on that so that the relief lasts for a longer period.
So, do the Back Settle exercise first and then in that position all you are going to do is to tighten your butt muscles (with very little pressure) and release.
You want to do these in a slow pulsing fashion. I do mean slow though!
Do a set for a minute and then take a 20 second break. Repeat 3 times.
Also, I know I hardly need to remind you, but do make sure you make it as easy to get up and down from the floor as possible. Use the chair for support and take care.
I believe that exercises for sciatica are the only genuine lasting solution.
Drugs don't do anything but mask the problem.
If you really think about it, how is a chemical cocktail going to fix a biomechanical problem. It's just doesn't make sense.
Now don't get me wrong. I do realise that pain killers have their place when you have to get on with life. You gotta do what you gotta do - short term.
Surgery is only treating the symptom.
Keeping in mind that sciatica is a biomechanical problem it might seem like surgery is the way to go, right? No, wrong!
The trouble with surgery is that, apart from being wholly inconsistent in achieving results, it's like trying to study a book by only looking at the page numbers.
You simply can ignore everything else that is going on and just cut a bit here or trim a bit there.
By doing the right exercises for sciatica you can deal with the issue in a way that will be effective and will last.
Here something to try right now!
Get down on the floor and (carefully) put your legs up on a chair.
Your butt should be tight against the chair and your ankles should be a knee height, so you might need to put a cushion under your lower legs.
If you need to you can put a cushion under your head. BUT only if you need to!
Your elbows should be on the floor and the should be below the level of your shoulders (hands on the floor or on your body).
Once you are in this position pay attention if your low back is flat on the floor (it won't be). Breathe from your belly and wait.
Stay there for at least 10 minutes - at least!
In about 80% of cases this will bring the sciatica symptoms right down. 10% of cases won't like this position at all.
If it does light you up STOP! and find a comfortable position.
If this helps, even just a bit, it's telling you that you should be doing a programs of exercises for sciatica.
Question then is, what are you waiting for?
