You can try a neti pot every day, it helps my sinuses stay cleared out. Saline spray also helps. There are some meds that some docs say are OK OTC but not every doc agrees so you'd need to ask your own.
I Also use a betting pot everyday and I feel Like It's The best Because It's not a medication and It helps clean out Ur sinuses as u use It.
I have a humidifier because I'm sick and also have nasal congestion since the beginning. It clears it right up.
I use an oil diffuser at night with peppermint and lemon oil
OK, thanks for all the advice ladies
