Question
im desperately in need of answers. i have always had a large chest a 38 DD but never any back problems. it was approximately 4 months ago that this horror begin. i had always sporadically been affected by charlie horses but i never realized that i'd get something so similar in my back. it's similar because both cause soreness the next day. my friend and i had gotten into a car accident. she smashed into another guy's bumper and we were both fine. approximately a week later i was woken out of a sound sleep but what felt like excrutiating back spasms on both sides of my upper back (where the bra opens & closes in the back). it hurt to breathe in and i just started screaming. i couldn't lay on my side because it made the areas feel like they were being pulled and stretched. i layed on my back and did deep breathing, two hours later these horrible pains disappeared. the next day my back felt tight. about a month later before a thunderstorm it started all over again. it woke me out of a sound sleep. it started off slow and before i knew it, there was daggers going through both sides of mid back. i took 2 anaprox and after 40 minutes the pain subsided. last nite was the third random flare up of this mysterious pain. it started off with feelings of tension in both sides of my back then 3 hours later it woke me up out of a sound sleep. this was the most intense i'd ever felt it. i couldn't even breathe in without a sharp pain going through both sides of my back. i was literally rolling around on the floor from pain. it lasted 3 hours and finally with anaprox it subsided. today my back is still sore. these pains remind me of charlie horses. it's like an extremely painful spasm. what could be going on with my back? it feels like a big cramp moving through my whole back. im in alot of pain...sound like a pulled muscle or something? im also very stressed. can stress be the cause? please help

Answer
It sounds as if there is a whiplash type injury.  These can affect the muscles, causing the symptoms you describe.  I would find a good chiropractor to asses and treat it, as well as set you up on a good rehab program to strengthen the muscles in question.
