I have a lot of back pain, what do you think i should do?
That depends.  What kind of pain are you having?  Is it more of a dull constant ache or a sudden sharp feeling?
Its really a sudden sharp feeling when im bent a little or doing something 
Lower back pain is very common and it can really complicate your life?  Is that where your pain is located?
Yes, i think im going a bit crazy, i actually train a lot, i think its because i was a dancer for 11 years
Have you ever seen a chiropractor about it?  A little spinal manipulation can go a long way toward easing chronic back pain.
I actually did, but i think he only made my situation worse! I think its also because i train really hard 
Chiropractors have faced a lot of criticism over the years, but it's most likely due to the inept few.  I've had great results from them.  Maybe you should try another doctor?
Yes the girl that did the think was still in school, maybe she isnt that good :D
Practicing chiropractors have a stringent code of ethics they follow, so you probably need to see a board certified chiropractor.   And ease up on the training!
