can sitting cause back pain - #24058

I am really struggling with this annoying back pain and just can't figure it out. I’ve been working from home a lot lately because of everything going on, and I'm pretty much glued to my chair for hours. Tried stretching and all, but I still have this nagging ache in my lower back. It feels worse after I sit for longer periods, like those 3-hour Zoom meetings. Can sitting really cause back pain that bad? I've read a bit about it and some blogs say if you don’t have the right chair or posture, it can lead to all sorts of problems. But I honestly thought it was just a annoying little backache that would go away. I mean, I'm not even 30 yet! I've been looking into exercises and considering a standing desk but wonder if there’s something more Ayurvedic I can do. Any advice on how to deal with this? Can sitting cause back pain, and how can I fix it? I see people say maintaining good posture helps, but like, what does that even mean in practical terms?
