Adrenaline carried through in that moment and allowed me to keep on. So I didn't feel it instantly. But five minutes later I noticed a sharp burning sensation, that it hurt for me to rotate my eye, that I had some serious swelling going on. Then it started to hurt in the back of my neck/head. Then I noticed I was quite woozy.
But you shoulda seen the other guy. Actually, this happened at work (Behavioral Health clinic. Most of the patients there were oversized teenage boys with history of violent crimes or even rape. This was one of the really oversized ones, and he had assaulted three other staff members that week), so I didn't try to punch him back. I just put him in a temporary hold until my partner could assist me in a different (transport) hold. We took him to a solitary area (just to remove the scene from the other patients. We were on camera at all times, so no abuse happened) and called the nurse so she bring in a sedative.
