To anyone in the Arlington, VA area, or within a reasonable drive thereof, I can recommend my ART (Active Release Technique) Chiropractor, Dr. Travis Hart of Arlington Neck and Back. There's also an office owned by the same people in Gainesville, VA.

I tweaked something in my upper back, under my left shoulder blade, about 2 months ago after driving a few thousand miles in a week. That road trip left my entire neck, shoulders, and back screwed up. About half a dozen visits with Doc Hart took 100% of the pain away, though I felt much better after only the second visit.

Instead of classic chiropractors, ART docs concentrate on muscular injuries and the pain that is associated with them. Just pushing on the spine doesn't do much, and is not a cure - only treatment. Stretching out and healing the proper muscle groups will allow your spine to realign itself and will get you back to your daily routine with far less (if any) pain. Doc Hart cured some pains that I had been experiencing for so long that I'd forgotten about them.
Obviously, continuing to drive around for long hours, wearing body armor, etc., will deteriorate the situation, so you will need to continue visits to your ART doc...but if you got the treatment that I got, you'd understand the value of what these doctors can do.

Glad to hear that you're already feeling better. Swimming is a wonderful form of exercise and therapy as well!
