Vaccination Relation?

So, it was weird... 

I had one of the seizures where my right arm locks up. It was more painful than usual, and the hand was in the claw-like position, not curled up into a ball. It was hurting for 20-30 minutes, a bit longer than usual. Then the pain drifted up my arm, and settled right about where my vaccination spot was. It stayed there for several hours, fading a little after about an hour. It's still a little sore two days later.

Told you it was weird.
