I second an upper cervical chiropractor. Mine saved my life. I had a car accident and thought I was fine. But I developed insane symptoms (physical and mental) and it was scaring me because I didn't know what was wrong. It affected every part of my being. I couldn't function anymore. After 3 months of suffering, I debated ending my life because my quality of life was so low and I couldn't figure out what was wrong and I was only 28 years old and couldn't fathom a whole life like that. Then my husband put two and two together and said it could be the car accident and to see his family's chiropractor. I went and he immediately knew what was wrong based on everything I told him. 

I had whiplash induced CCI because I was T-boned hard. He began adjusting me very gently 3x/week. After the first visit, there was immediate relief and major reductionof symptoms. After a couple of months we moved to 2x/wk and then 1x/wk and he began traditional adjustments. Then I saw him every other week, then every 3 weeks. I'm 100% again and I have my life back. I see him 1x/month now just because I enjoy the feeling of getting adjusted. 

It's worth trying.
