I'm gonna sound like a infomercial but maybe others have been having issues too...
For the last 2 years I've been developing some extreme lower back pain.
I couldn't stand for more then 10 minutes and some of my toes were starting to go numb.
I've tried everything, (doctors, chiropractors, physiotherapists) almost to the point of surgery.
After sitting all day behind a computer at work, and then going home & sitting while I work on music at night.
I decided to try one of these https://www.varidesk.com/
Right away my issues have started clearing up.
A cheaper option, my brother did installed a large shelf on his office wall where he
can move his laptop to and still stand. He said it's helped him too.
Might be worth checking out?
Side note...My chiropractor suggested stopping every hour to stretch for a couple minutes. That's helped
a lot too.
