Pain behind eye and left side of face numb after push ups

See doc asap. Numbness in the face sounds neurological. BOL.

It happened to me when I was having a wank

Could be migraine, especially if you also have any vision disturbance but you should get it checked out ASAP

Sounds like a neurological issue, most likely a stroke, see a doctor.

Sounds like a cardiac event to me. I'm with everyone else; go see a doctor.
