kev,

Do you have a recliner chair ? If so, try sleeping in it. Get yourself in a comfortable position where you can just melt into sleep. See of you can sleep longer that way. Early on, I had to change my sleeping position so I did not aggravate my neck and cause inflammation and spasms.

Recovering from a concussion often takes experimentation. Finding your head ache triggers is quite a task but an important one. It may help if your wife is very gentle with your neck. Some gentle traction with gentle mobilization may be better that pushing for range of motion. Stretched and strained ligaments need a gentle approach. C-1 and C-2 strains can be very difficult to heal.

Do you jaw clinch, maybe when you are sleeping ? I did early on. It caused severe TMJ problems. I took gabapentin before sleep and it helped reduce my jaw clinching. Do you sleep with one side of your face on your pillow ? Sleeping position can exacerbate a jaw problem.

Your head pressure is worth investigating. Ask the neuro about it.
