Sinus Medication Solution

I normally get a sinus infection this time of year and I think its coming now. I start with the feeling of major drainage in the back of the throat.
Is there anything I can do NOW so I don’t feel really horrible?
It might not be a sinus infection but its feeling that way right now.
Thanks
oh and I can’t use the nasal rinse stuff. I just can’t do it.

I’m miserable and can’t get to the doctor til this weekend. Also what can be done about repeated sinus infection all winter? I get them constantly.
