i can'at find any listing for the side effects you detailed. and your dosage is small. i think you should call your doctor manana and talk to him/her about this. try some heat, moist cloths, on your sinus and sometimes it is helpful to fill a basin with hot water and put a towel over your head and breathe the steam in.....be careful though..don't get it too hot.......i'm hitting the hay....long day....let me know tomorrow how you are doing. pat
