Ok so im prone to them and have another its been going on since week 4 so 9 weeks. Last week it got so bad i gave in and got antibiotics but they only gave me 5 fays and it came back as hadnt quite gone so now on another 7 day course!!!! 
Any one else suffering with sinusitus? 
Nothing seems to help and we cant take much. I just want my face to unblock so i can sleep properly again argh
