massage therapy is mostly a scam and will not help a chronic back problem. the reason? it makes no sense to work an area that is already hurt, pretty simple logic.. same thing with chiropractors, cracking your back does nothing to fix the problem.
you need to fix your posture and stretch out the muscles often. I would honestly get into hot yoga, it kills 10 birds with 1 stone and it is something you can do with your gf. I do yoga after EVERY workout
