Home remedies for sinus infection, anyone?

So today was day five after I tested positive for covid and I’m now negative, thank goodness! But now I’ve developed something that is either a sinus infection or at least a cold in my eye. Of course, it’s Sunday, so I can’t get a hold of my doctor. I could have gone to an urgent care place but wasn’t really feeling strong enough to go out.

I know there’s all sorts of over-the-counter stuff that I could order and have delivered, but I’m a complicated person. I have high blood pressure and kidney disease in particular, so there’s a lot of medicines I can’t take.

I did buy a humidifier on Amazon which will come tomorrow morning, but if anybody has any other suggestions for things that will help, I’m more than willing to listen. I figured tonight is going to be pretty miserable either way.
