Ugh, this is just SO ridiculous. How is possible for my nose to be STILL plugged ONLY and consistently in the left nostril?
I went back for an X-ray yesterday from the original dentist who referred me to the endodontist to get the root canal and he said there was no sign of infection around that tooth.

So could the cleaning of the canals during the root canal have led to infection into the sinuses? Like it's actually ridiculous how clear my right nostril is, in comparison to my left.

I guess I can continue breathing through my mouth until winter is over and people believe me when I say I don't have a cold ... I don't know if the removal of the tooth will help with the sinus though? I guess once that source of infection is gone..
