COLD, FLU, SINUSITIS OR HAY FEVER.
WHAT DO YOU HAVE?
A cold, flu, sinusitis and hay fever all have one thing in common; they’re conditions of the upper respiratory system.
Colds and the flu are contagious and caused by viruses1, whilst hay fever is a reaction of the immune system.2 Sinusitis, on the other hand, is an inflammation or infection that usually develops as a result of a cold.3 So whilst some symptoms can be similar, these four conditions are all different, and so should be treated differently.
It can be hard to tell what you’ve got, and what you need to feel better fast. So, read the articles below to find out how to relieve what you’re suffering from.
