I’ve had the same pain since the late ‘80s. It was always a precursor to an outbreak. The pain was terrible, sometimes my foot felt like it was getting hit with a hammer! Thank God Valtrex came along, it gets it under control quickly!
No, it's not spread through the body. Herpes infects nerve groups, and can only travel through the specific nerve group that is affected. For example, genital herpes will never travel through the body to the eye. You can autoinoculate (touching your eye with an infected finger), but you have antibodies (if your test is positive). Do you have your test results in hand? Like the actual lab report? Can you ask for a copy of it if you don't? Does it give the reference ranges on it, like what's positive, negative, etc?
Ocular herpes has pretty clear symptoms. You'd be at the doctor in no time if you had it.
