Get to an RA doctor and have him check you for Fibromyalgia, CFS, Lupus, Lyme disease, RA and whatever else he can think of. Good luck. I feel for you, I have chronic pain and more than once woke with rib pain so bad I couldn't breath. You could be having muscle spasms from the dislocation too. You might want a muscle relaxer or get some magnesium, that helps ease muscle problems. Also soak in ebson salts bath before bed.
I had a very similar thing happen to me, I awoke from my sleep with a feeling of a knife in my back right between my shoulder blades and slightly to the left. I found a osteopathic manipulator after a month of debilitating pain to "fix" me initially but required several treatments and physical therapy longer-tem. However, I am not home free. I still have what I call flare-ups that will keep me down for 2-3 days sometimes a week at a time. I am 33 with two kids and work full-time, no time for messing around with pain. This has been going on and off for 5 years, ever since my first prenancy. I fell at 4 months and knock my pelvis/scarum/tail bone out of place. I have found ways to manage with the pain - Biofreeze, tiger balm salve, OM, PT, accupuntcure, massage, epsom salts bath, advil, specific exercises, etc... Unfortunately I feel like I can't ever exercise to the level I would like for fear of throwing something out and causing a flare-up. I used to be very active (biking, hiking, etc...). I hope to get to do these activities again.
