Hi everyone! I am new to this forum and hope some one can help me.

I have been getting headaches on and off for the last week. I have been starting to get pain in my neck and my head aches have gone away. I got into a car accident 6 years ago and got minor whip flash from the accident. Tonight when I was washing the dishes my neck pain moved over to my right side only and I have a weird feeling in the right side of my head. When I seem to lay down for bed the pain goes away. I have an appointment to see the doctor on Friday to take x rays of my neck. Any ideas on what could be causing this?!? Any information would be great! Thanks in advance!!
