Me and my cousin both have Sinus problems. He took Sinus surgery before but it came back in less than a years time. Me too have sinus,as bad as I need to prepare tissue for most of the time. Last year I went to Chinese medication , and I was advised to stop eating chicken. So I did not had any medicine nor surgery , just stop eating chicken since last year.Now I rarely encounter any Sinus problem like I had before (touch wood ),but sometimes still happen, may be only once every half month. So guys if you can give up chicken for a week,it worth a try to see if there is any improvement.At least it worked for me.
