Pawel is not well

[Tom Lowe]

Pawel, just a random tip. Not sure if it is relevant to your current situation.

When I was about 20 I hurt my back pretty badly by trying to lift some heavy crates. It did not heal well. After weeks of stalled progress, I bought a $20 USD neoprene back brace from a sporting goods store. Similar to a weight-lifting belt. It had some vertical slats in the lower back area, and when the belt was tightened, it helped to immobilize my back. After wearing that brace for only a couple of days, my back quickly got better.

I know what you mean about not being able to sit still. With me it's very chair dependent. Some better than others, and sometimes, it's not the chair, but me. Good luck finding really good chairs for your computer work.

I sometimes suffer from lower back problems and my Chiro suggested sitting for a short period on a Swiss Ball,not sure if you have these where you are,but it's a large rubber ball used in the gym for exercising and strengthening the core muscles,but also to relieve tension in the spine. Seems to work for me,although you do look a real dick sitting on it. Best to get some advice before trying though.
The best chair I've found is the Aeron chair by Herman Miller, www.hermanmiller.com.
Hope things continue to improve for you.
Tom.
