Hi, I Am An 18 Year Old Female. About 4

Hi, I am an 18 year old female. About 4 years ago I cracked the C6 tail in my neck playing basketball. I didn't need surgery, I just wore a neck braces for a few months. I was 14 at the time. I have been having neck and back pain ever since and my mom took me to a chiropractor in February, almost 3 years after it happened. It has helped but I still have pain to the point where I'm staying up all night because I cannot sleep. I've tried ice and heat. Ibuprofen, muscle relaxers, nothing has helped. I've been to the chiropractors and my local doctor many times and they just tell me it's muscle spasms. I cannot bare this pain any longer.
