How do you tell whether an attack is a cold starting, an allergy attack or non-allergic rhinitis from some other trigger?
I had a bad sneezing fit totally out of the blue a few days ago; went on dripping all night. OK the next day, then similar attack next evening. Mild headache. Pollens are very early this year here, so I couldn't make out what was going on.
Decided in the end it was an odd, short-lived cold. Luckily, symptomatic treatment is about the same regardless: Old (type 1) antihistamines, decongestants & OTC cortisone nasal spray. And it was over in 3-4 days!
