Julie, there are good and bad chiropractors just as there are good and bad "real doctors". You just have to do your homework and know who you're letting treat you.
You may have a condition that is easily treated by a Chiroprator and then again you may not. If it were me I would talk to my PCP and get their opinion on whether or not they think a chiropractor can help you. If they have done all they know to do and you're not getting any relief they may feel that a chiropractor may help.
Good luck to you!
