Only time a shot has given me a feeling I would describe as abnormal is when this south paw caught me flush on the chin with his left hook.

Didn't get rocked/see a flash/loose hearing or what ever but more Jaw felt like when the Dentist numbs your mouth with an anisthetic.

didn't normally but a few weeks prior to that felt my right hand kept wandering from my jaw where I usually hold it so that's probably why I got caught.
