I pretty much have been feeling crappy for the past week, due partly to an unsettled stomach and partly to a pain in my neck. And shoulder. I went to the chiropractor on Wednesday hoping he could pop things back into their correct locations, and while I'm sure he was successful at aligning my spine, he got no where near fixing my shoulder & neck issues.
My neck feels stuck because when I turn my head too far in any particular direction I experience shooting pains on the right side of my shoulder area. This made sleeping kind of difficult because anytime I changed position (probably 10 or so times that I remember) I woke up wincing and inadvertently whispering unpleasant words. It's the kind of injury (let's call it that, because I don't know how it happened) that makes it difficult to turn my head while driving, you know to check my blind spot or to look for anything/anyone behind me before backing up. And it's almost impossible to talk on the phone, since the only time I'm really on the phone is when I'm also doing something else like emptying the dishwasher, putting stuff away, retrieving the cat from the back yard before he tries to jump the fence again ... so I'm usually holding the phone between my shoulder and my ear. I physically cannot do this right now because of the pain.
Each morning I wake up stiff but by the time I'm crawling into bed at 9:30 my shoulder & neck finally feel somewhat relaxed. Just to start all over the next morning. This morning I finally made it to the gym and got in a decent work out and I really feel better for doing it. I was very close to blowing it off because my stomach wasn't 100% and my neck was hurting, but I went and now I have more energy. I still experience shooting pain near my shoulder but I don't feel as "blah" as I have this whole week.
So my advice to you: be active because you'll feel better. Or like the advertising geniuses at Nike say, "Just Do It."
