Hello mawrn,
Welcome to NeuroTalk.
I was wondering if this sensation you're feeling is pain or is it more a tingling? If it isn't a painful sensation then that may help you narrow down the cause (or the name). The key may be that when you press on a certain area the sensation subsides... just a thought.
Look up the definition of "parathesia" in the dictionary and see if that sounds like the sensations you're having.
Do you get migraines at all or have you had a recent head injury or any recent dental work?
I'll leave a couple of links to forums here where you might want to ask.
Occipital Neuralgia and other Cranial Neuralgias forum
Headache (includes Migraine) forum
There may be information in the "Sticky" threads at the top of those forums that is useful even if it's to rule out certain conditions.
You could also ask on
Dentistry & Dental Issues Forum
I hope that's not an overload of information. I also hope that you get some answers soon.
take care.
