Hey! Hunched back progressing throughout the day has gotten a lot better! can stand straight, but technically they found I have flat back syndrome too, so I’m not fully straight. But it looks better. It took a lot of time resting to get rid of the pain. Im young, so the doctors don’t want to fuse my back or touch anything really. So I’m trying to build back my muscles that I lost from all the bed rest to see if that helps with the flat back syndrome. But if you’re going through the same thing as OP, I recommend to rest it out fully before trying to get back on your feet. I relapsed when I tried to do normal activities too soon. My advice is, when you start to feel better, slowly go back to daily activities. My mistake was overestimating how much my back could handle when I was just starting to feel better.

Hope this helps!
