i have had sinusitus for 8 years and use nasalnex to prevent inflammation. i have ran out and havnt had it for about 4 months. i was doing quite well without nasalnex but have had a bad time with my sinuses the last 3 weeks. i have to use co-codamol on a daily basis to kill the headaches. today someone told me chocolate aggravates it. is this true because i have been eating a lot of the stuff the last 3 weeks and this could explain things.
