I'm 6 months into my PCS now and I tried a chiropractor, for the second time (first one was a Quack, long story) last Friday. She said my C2 was out of alignment and this could have something to do with my bad headaches. She re-adjusted it but stated that I will need to return once a week for a little while to ensure it stays adjusted because it will slip out of place for a few weeks. After a while it should stay in place without adjustment. So that's good that they are ensuring that his C1 and 2 are continuously adjusted and not slipping out of place. I admit that I am feeling a little better after the chiropractor but this may also be attributed to my increasing of my amitriptyline dose from 20mg to 30mg last week as well. I am hopeful that at the very least having my vertabrae adjusted to a healthy order will help speed my recovery if it doesn't directly have any effect on my headache symptoms. Definitely recommend a Neuro though so you can approach this from two angles.
