Hi,

I had a sinus problem. 4-5 years back I had an operation and I hope it cured.I got cold since 1 week back, till yesterday I was Okay and didn't use any medicine (Generally I don't use medicine for cold, mostly it will be cured itself within a week/10 days in my case). I was getting brown mucus (very little) before today (23/11/2015) I am getting only brownish mucus at one nostril only. Is there anything that I need to worry. Thanks in advance.
