Tic de la roux - trigeminal neuralgia. Feels like ice pick in ear or burning cinder in ete.

Yes I do get them usually when stressed and tired bofore a flare up let me know if you find out for sure?!!!

I have had these, they hurt & they're scary bc it's our brain. Doesn't seem right having such extreme "zaps" to your head. lol Mine mostly came at nite & most often ended up becoming a pretty bad migraine. That's just what experience.

I get that from time to time too with a burning sensation right at the base of my neck

I call them electrical shocks. my neuro says normal part of MS, although mine seem to be in the areas where MRI shows plaques on brain. I take Gabapentin(Neurontin) and my neuro has increased my dosage to help with the pains. I still have them some, but is better.
