I just had the same thing last week. I found musinex to help the most. It helped with the non stop runny nose. I ended up having strep and an ear infection as well though. Hope you feel better!
Saline spray, warm shower, steam up the bathroom and just breathe, peppermint oil (not directly on the skin unless you mix with a couple drops of olive oil) to help you breathe a little better (maybe touch it to your sinus area or put a couple drops in a diffuser). Also, I found massage helps. A circular motion over my sinuses, and nose.
I had a terrible sinus infection 2 weeks ago, I ended up going to the doctor because it was so bad I was unable to sleep. They had to put me on an antibiotic, none of the OTC medicines worked me me. Flonase helped a lot too.
Re: HELP! So sick
Afrin helped me but gave me a migraine
