My doctor recently suggested that would I have thought has been a high number of colds the past 5 months has really been an allergy to something in my work environment, she suggested that I take antihistamines and prescribed a nasal spray with a steriod in it help. However I have been on these for just over a week now and I am having symptoms return... is it possible to continue to have the same symptoms even while on these antihistamines?
