Don't use a Neti Pot. Depending on where you live, you can pick up a brain-eating amoeba called, "Naegleria fowleri". If you want to use one, make sure you put the water that you're going to use first, into a pot and boil it, then put the water back into the Neti Pot.
Some other natural remedies:
-Use a humidifier or vaporizer. -Take long showers or -- very carefully -- breathe in steam from a pot on the stove. -Drink lots of fluids, which will thin out your mucus and may help prevent your sinuses from getting blocked up. -Use a nasal saline spray – simple unmedicated salt water – to help prevent your nasal passages from drying out.
I am in the same situation. Not fun! I have 4 meds from my dr and yesterday and today seems to be horrible! I stream my bathroom and take a long hot shower or if I can't because the kids are up running around I will boil water and take it off the stove and stick my head under a towel and just breath in the stream. Hope you get to feeling better soon.
