Yes i did this as it hurt even when i sat in a chair.

Go see a chiropractor for god's sake! They don't cost that much and you'll not regret it. See one who's been in practice for at least a few years and has established himself. Word of mouth advertising is best. Get recommendations from friends, don't just let your fingers do the walking. Just because someone can afford a full page ad in the phone book doesn't make him qualified to work on your back. Good luck!

Firstly, Yes!! Go see a choripractor! The one my mother trusts uses an x-ray machine for an initial look at the problem before making any blanket prognosies or begining work on an unfamiliar unhealthy back. At least as I recall he does, it has been years.

Secondly, You need to find good instruction or literature about non-harmful stretches and good posture. For non-harmful stretches I recomend a book called Surviving Exercise I think it's by Judy Adler. For good posture the only book I know of is Exercise Without Exercising Its an oldie and hard to plow through but good posture is important for keeping your muscles in condition to keep your spine in line, if that is your particular problem. A neighbor of mine with chronic bad back pain due to a real medical problem in her spine after using the stretches in Surviving Exercise that were specificly for properly stretching the back experienced a significant reduction in her back pain.

So get your problem checked out and fixed and then do what you need to to keep it from becoming a problem again.
