Don't ignore back pain guys. Seriously

Coding overnight, constantly hunched over my desk, triggering a dull, burning pain down my lower back and legs. Two months later - SI joint pain kicked in. Shooting pain, discomfort sitting, standing, even lying down felt off... wish I had taken care of my back earlier

My doctor told me my bad posture was culprit with cheapy chair and too much sitting from grinding sessions. Now I’m stretching daily, using proper chair, and huting for a standing desk to mix things up. Anyone here dealing with the same thing? what's your advice? is there anything that I can get like sit stand desks, stool chair or other setup upgrades that could help?
