chiropractor?

why is it i can see a chiropractor and after a few weeks with her i feel no migranes? i mean i saw 1 and i never had migranes for 4 weeks and wow this is like the 1st time in 5 years ive not had them,i felt reborn again,and i go to my doctor at the hospital and he gives me lyrica which ive read alot on here says its awfull and the side effect are terrible.if i could afford it i would see a chiropractor every month,but because i suffer migranes daily i cannot work which limits my money spending
