Hello gato,

Welcome to the NeuroTalk Support Groups.

I'm sorry you're experiencing these symptoms for so long.
Do you get any disturbances to your vision at all?
There are so many different types of headaches with varied causes and symptoms.
I get migraines from time to time myself and I know that there are many, many different types of migraines.

I'll leave the link below to the
Headache Forum

and

Occipital Neuralgia and other Cranial Neuralgias Forum For discussion of Occipital Neuralgia, Glossopharyngeal Neuralgia, Nervus Intermedius (or Geniculate Neuralgia), and Vegal and Superior Laryngeal Neuralgia.

There are some threads at the top of the forums and they contain useful links, resources and other information.

Hopefully your MRI is soon and your doctors can figure out why these headaches are happening. Try not to make yourself more ill just worrying about it. Easier said than done I know.

take care there.
