My back muscles feel like they gave out, what do I do
I have had bad posture for a while now, and I’m very well aware. However, yesterday while hunched over my computer, I could feel my muscles genuinely trembling and it seriously felt like my back muscles fully gave out. Ever since then my neck, shoulders, and back have hurt especially bad compared to usual. Did my muscles actually give out?? What can I do to improve my posture??? This was a huge wake up call for me and I’m kind of freaking out and don’t know what to do!
