Been there, done that, made the threads.
Here's what brought my pain from excruciating to almost zero in two years:
Drugs- oral steroids for the immediate injury and then later Savella for the chronic pain (do a search in wf for my post on that)
Egro- Fix your sitting situation. Make the angle of the screen appropriate. If you have two make sure you have both as close together and to the center as you possibly can. Keep your elbow touching your ribs. Invest in an egro mouse. The one that's like a joystick did almost immediate wonders for my wrist. and most of all GET AN EXERCISE BALL. I can't stress this one enough. Not only is it the perfect chair (cushions your ass unlike anythng else out there and forces you to sit properly) you can take a break and stretch on the ball in ways you will never ever be able to stretch without it. I'm serious, if you skim everything in my post, get yourself a fucking swiss exercises ball k?
and then of course any type of core exercises will strength the area. But don't even attempt these until the inital injury is mostly healed.
Again, I've suffered back and neck pain for 20+ years, it's pretty much eradicated as of this moment due to all of the above.
(and dump the chiropractor, not only are they complete quacks, he actually injured me further. I mean who the hell attempts to forcefully move an area with constant swelling? A quack chiropractor that's who)
