I am a long time allergy sufferer (50) years.  Asthma since childhood but totally controlled with Advair.After 30 years of allergy shots and , I have had no attacks to speak of in the past few years. Occasional nasal polyps.Yesterday afternoon I had what seemed as an immediate allergy attack. I have taken my standby antihistamine Chlorophenaramine with no affect.  Also taken 40mg cortisone which my doctor lets me keep on have for colds that seem to move to my  chest to be taken at my discretion.My upper right nostril is extremely sensitive and pouring mucus.  Should I call my allergy/asthma doctor on a Sunday?Mel
Yes you can as physical examination will be best to diagnose reasons at present the answer to your question is in allergies the mucosa of nose become sensitive and even a slight temp change in air going through nose affects the sensitive mucosa causing excess mucus formation till you see your doctor can use anti-allergic tab along with application of Aureomycin hydrocortisone ointment in nose twice a day and hypertonic saline nasal Chat Doctor.
