Hi there. Yep you are right as regards the usual incubation period. However, yes it may also show up 3 mths later but unlikely after a year assuming you have been celibate for a year!! Having said that, i doubt the symptoms are related. It is very possible the eye symptoms & the burning urine & stomach-ache are un-related. Most probably you have some minor stones et al in les pipeline that need some further investigation. Try popping a few beers alongside plenty of water to flush this out. If not, best to see a urologist on the ground. Couple that with an earlier visit to the opthalmologist & you will be reassured. One way or the other, the eyes need to be addressed asap! Cheers & do hope this answer has helped you make an informed deciscion. Wish you continued Good Health! Dr Praveen Rodrigues MD
