Increase in crown of the head pain when leaning forward?

The title says it all really...I started my pain (4 months ago) journey with classical occipital neuralgia pain then it jumped to the left side of the crown of my head (and then left ear pain started and tinnitus went through the roof) and I'm dealing with a lot of transient pain in the top of my right eye socket right in the back. I was wondering though. Whenever I lean forward (for example getting in to bed) I get pain in the crown of my head, heaven forbid that I cough or sneeze because then the pain is intense and gradually fades over 10 minutes. Anyone else getting this. (I'm on Tegretol/carbamazepine 400mg a day, Gabapentin didn't work for me)
