Wow, the tilted head thing is most likely fixable with upper cervical chiropractic.. MDs do not study this ..and rarely suggest it ,, the old MD vs DC controversy..
How about your shoulders, hips, knees are they all tilted or uneven? Same thing c1 c2 is out of alignment.. it all follows as body is trying to rebalance the weight of your tilted head on the spinal column.

Up C Spine has great info..

Some regular chiros can treat at a lower cost ( no fancy equipment to pay for ) if they studied it and use visual & leg length checks.
