Thank you Dr. Kutryb, I will mention this the next time I visit my GP. Thanks for your assistance.
It could be due to either overproduction of tears due to allergies, chronic irritation, keratitis, entropion (turned in eyelid), or other eye diseases - or due to improper drainage of tears into the nose due to blocked nasolacrimal duct, ectropion (urned out, droopy lower lid). You should be evaluated for all possible causes then after diagnosis, hopefully an effective treatment can be started.
