Wrist Aneurysm

Similar to a seizure, but begins at the hands/fingers and rapidly works up to the rest of the body. Wrist aneurysms are undetectable, but can be triggered by the victim. The victim will lose control of their body. One of the many symptoms of Ratpiss Disease.

Person 1: "Did you see that kid back there?"

Person 2: "Yeah, I think he was having a wrist aneurysm."
