Traveling hip pain

Hi! It is near the end of my cross country season and I am in some pain. When I run, pain is pressing in my hip/upper thigh. This pain has traveled to my lower back and now in my tail bone (coccyx?). I have tried stretching my hip and it is it pain when I do that. So, I am not sure what exactly is going on. I am going to the chiropractor tomorrow to adjust my back…maybe that will help? Any advice or comments would be helpful.
Thank you!
