Clogged tear duct or stye?

I'm having pretty bad pain in the inner corner of my eye. Especially when I blink. I could've possibly had an untreated sinus infection. How can I tell the difference between the clogged duct and a stye? Yes I know y'all aren't doctors but getting into the doctor during this pandemic is really hard for me. Please help if you're able to. Thanks in advance.
