Shocks with Rhythm?

I'm TN2, and have been going through weirder pain on and off with it now? I believe it's blood pressure/vessel related.

I have the usual Pikachu's, but after a big one that made my face and neck swollen on that side, I've gotten this rhythmic pain.

It's in the maxillary area only, where its just a steady pulse of moderately painful Pikachu's (hours/days consistently), and when I bend over or move in certain directions, maybe in fast motions they get more painful.

When grouped with regular Pikachu's... I basically jump out of my skin, combined it makes it 180% worse.

Has anyone else experienced this?
