Before I started exercising it seemed like I had to see my osteopath almost monthly. I'd pull my shoulder out or my hip and be in agony, until my doctor would straighten me out and align my frame. He'd always start with my feet and comment how one leg was longer than the other or some such stuff. Then he'd begin his manipulations and if I wasn't feeling better when I walked out of his office, I was by the next day.
Since I've been exercising regularly, I don't need to see my doc so often, but I do try to go every three months or so to make sure I'm keeping everything lined up. This is important for me, it's sort of a check in to make sure I'm in good muscle balance.
I went a few weeks for one such check in and actually had a shoulder that was complaining (an old injury that likes to flare up every now and then). He fixed me right up, but it made me realize that I had been forgetting to exercise my rotator cuffs. Its an easy thing to forget, they seem so insignificant but if your rotators are weak, it compromises other exercises too like bench presses.
Speaking of forgetting to exercise small muscles, there are others you shouldn't ignore. Here's a great link for how to exercise often forgotten muscles, including rotator cuffs.
