General tightness in upper back
Hello, for the past year or so I've had a general tight feeling in my upper back. It seems to come and go. Sometimes I'll go a week without noticing it and sometimes I notice it every day. This isn't a big problem, it's not painful, just rather annoying, but I thought I'd see if anyone has had similar issues. When my back feels tight sometimes I can crack it by pushing back against the back of a chair in a certain way (after this long I have it down to a science) If I can get it to crack (not one big crack, but it sounds like lots of little cracks at once) it feels GREAT and my back will feel brand new for anywhere from 30 min to a few hours, then it's back like it was before. Tight and uncomfortable. I've been blaming it on stress, I know many people "store" tension in the upper back so maybe this is what's going on? What do you think?
I'm a 22 year old male, 5'11", 215 lbs. I'm a full time student, so I do sit still quite a bit, but I also have a part time job where I am up and about and moving heavy things around almost every day.
I'm open to comments / suggestions
