To make a very long 32 year story short: NasalCrom has rescued me from terrible sinus headaches for 32 years. A doctor once told me I have "asthma of the sinuses." And he was right,because NasalCrom is asthma medicine in a nasal spray form. I only wish I had NasalCrom for the past 32 years instead of constant antibiotics and millions of pills. Oh well - better late than never! It's cured me from my dreaded headaches by about 95%. I wish you all could find a miracle cure like I did.
