Sit stand desk
I've been trying many things to try and help the sciatica. One of the things I've tried is a sit-stand desk, very similar to the one in the photo - it's a Yo Yo desk. (but mine has the risers crossing in the centre rather than at the side)
Has it helped - yes, I think it's been an overall improvement. The sciatica still hurts, but I've noticed an increase in the time I can spend sitting down - which makes a bit difference when board gaming. It's as though I have a ration of how many hours I can sit for, and standing at my desk helps me use those 'sitting hours' for other things.
The think I most noticed when starting to use the desk was that I got a lot of pain in my calf and other leg muscles.
I'd noted this as a potential problem from people writing about their experiences with standing desks and it's why I went for a sit-stand desk rather than a pure standing desk.
Being able to lower the desk again when I needed to ease out my legs made a big difference. Now I've been using it for a month, I find I'm choosing to use it standing for most of the time. I'm often more comfortable that way - but I can still sit down if I want to.
It was the fact that the desk could be easily adjusted from sitting to standing that sold it to me. It needs a bit of a yank, but there's assistance from a gas lift and it really isn't too difficult.
I got this one cheap as it was a return, and I've no complaints.
One side effect is that I've noticed my leg muscles are getting stronger. I can feel the difference when I'm doing morris.
Would I buy it again? Definite yes.
I notice they've still got some returns - https://mailchi.mp/8283b51ff5a6/clearance-sale-off-sit-standcom-limited-period-offer-284022?e=%5bUNIQID - and their sales guy was very helpful when I bought mine.
I'd definitely break yourself in gently if you do get one. Try standing for 10 mins every hour to start with - you spend less time on your feet than you think!
