I have had an infection partially block one, and it was painful. It prompted me to go to a doctor even though I did not have insurance. I had to take antibiotics for a while, but it got better quickly.
At least you have an infection to blame it on. For me the partial blockage was the first symptom, so my worry was partially about it being possibly caused by a tumor. I was relieved when I had other symptoms that pointed to an infection.
