ooh that sucks! there was no swelling associated with my injury, so the bed buddy was my new best friend. i must have nuked that thing 100 times.
i wouldn't go back to the chiropractor if i were you, if you need to seek therapy i'd just see a masseuse. another thing you can do that helps is ice massage. if you can handle the touch of bare ice, rub an ice cube on yr sorest spots first. once it numbs you a bit, you can press harder and really hit the deeper muscles. i had to learn how to do that when i knocked my kneecaps loose. it sure is hard to numb muscles and ligaments that are under the kneecap
you could probably request an ice massage from a masseuse too, i'd think.
after the ice massage, lay down in bed or on the couch with your head propped up in a position that is comfortable, with the "bed buddy" under your neck. relax all your muscles as much as you can and let the heat do its work. afterwards, you should be feeling pretty flexible, so move your neck around and try to exercise it a bit. if there's no improvement after a week, you should probably see a doctor again and get some xrays done. if the massage/heat/exercise doesn't help, its probably more than a muscle strain!
its nice (kinda
) to know that someone else gets injuries in their sleep! i thought i was just accident prone or something. my last sleeping injury was...i fell asleep on my stomach with my arms tucked up around my chest. i woke up in the morning and my hands and wrists were blue
they felt completely dead. after a couple hours, they swelled up about twice their normal size, turned bright red, and hurt like crazy! i couldn't use my hands for 3 days
my knuckles stayed swelled for about a week.
