Hey guys, just for context I am 20y/o 6’3 around 220 pounds, I struggle with really bad back pain. Sometimes in lower back but mostly in upper back. If I am sitting down I can barely look down without a shooting pain in my right shoulder blade. When standing if my back is straight I also feel super locked and can’t move it much. I work in IT and sit for for around 10 hours a day. I do try to stand and stretch but no as often as I should. If I stand up with legs separated I can’t touch the ground nor really get close. This is starting to concern me a lot as I am young and can barely move freely if at all. Any suggestions would help. Thank you
