Sleeping,

Try some ice on your upper neck and/or forehead and see if it helps with your head aches. And, stay away from end of the year partying and booze.

If you have a soreness behind your ears, you may need some therapy for your upper neck. The muscles that attach to the skull behind the ears can get caught in spasm as a result of minor upper neck injuries and instabilities.

Have you tried closing your eyes to help yourself concentrate? It can be a big help.

My best to you.
