Nedi pot symptoms and conditions

I had terrible sinus problems combined with my deviated septum. Swollen nostrils, constant nasal drip, couldn't sleep at night, and terrible sore throat in the morning. Started taking nasonex two months ago... Stopped all my problems in a few days. After two weeks I was only spraying each nostril once about 2-3 times a week. My periods are always every 28 days and my past period was 10 days late, I am still waiting for this months period (over a week late). I realized it has to be the nasonex. Along with menstrual problems, I have had terrible nightmares, acne problems (for the first time ever, I'm 24), a few nosebleeds, headaches that have lasted over 4 days, and itchy skin. I didn't put it all together until I saw this website. I will not be spraying my nose again, from now on I will be using the nedi pot.

While taking this, I have experienced water on my knee, aching in my leg and then a problem with the right knee, aching in arms and shoulders. All of this could be something else, or at least the fluid on my knee. I had an MRI Saturday and will hear in a few days.
So what is the best med for sinus infection which is why I am on this.
Thanks.
