Chiropractor and migraines!!

So I posted the other day about having a chiropractor appointment. Well he did an X-ray then on my neck. I actually got a pic of it 😂 you can see the alloy mesh plate where they replaced part of my skull from my surgery in 2014! (Had a large tumor that damaged my skull too bad for them to put it back.)

You can also see where the vertebrae in my neck are locking up. Yay me! He thinks that could be what’s causing my migraines. Well, he did a few adjustments on my neck and my upper and lower back today. It helped some!! Yay! My question is: how many times did it take to really start seeing a difference for y’all?? Bc my head doesn’t hurt as bad today as it has been, but it’s still a nag. (Nothing unbearable!) I also thought the X-ray looked cool 😂
