Hi,
I have been complaining of severe headaches and stab pains in my head/ ear/ jaw/ cheek and all over my head - well I found the cause !
It is called Trigeminal Neuralgia - it is a nerve that is being pinched or irritated by something. In my case by an enlarged(bubble) blood vessel.
I have to be on permanent pain meds. But not the normal pain meds - something that takes the edge off the nerve. It then reduces the "stab"
The things we go through !
