The symptoms and the severity of hayfever can vary widely from person to person and also depend on the type of pollen a person is allergic to. Common symptoms include:

• Sneezing
• Runny nose 
• Nasal congestion
• Coughing
• Itchy eyes, ears, nose or mouth.

Less common symptoms include loss of smell, facial pain, headaches, earache, tiredness and fatigue.

Many sufferers are often confused about whether they have a cold or hayfever. One of the key differences to look out for is how long the symptoms last for. A cold will usually clear up within two weeks, but hayfever symptoms will persist for longer.
