Summer is here. The sun is out, flowers are abloom, and hay fever is in the air.
One in five people suffer from it, so for those unlucky enough to be one of them, brace yourselves for months of torture.
Your eyes will itch and stream, your throat will be dry and itchy and you'll sneeze.
You may even be scratching and itching just reading this - it can be really debilitating for those living in areas with high pollen counts.
It is easy to dismiss long-term coughing and sneezing for an ongoing cold. But if youve had a cold for weeks on end with no sign of improvements, chances are, youve got hayfever.

So what exactly is hay fever and what can you do about it?
Simply put, when you have hay fever, your bodys immune system treats a harmless airborne substance as harmful, producing antibodies against it.
This means that next time you come in contact with the substance, your immune system is signaled to release chemicals that cause a reaction leading to symptoms of hay fever, into your bloodstream.
You can get hayfever at any age, but it usually begins in childhood or during your teens.
It's more common in boys than girls, though adults are equally affected.
Experts aren't sure what triggers hayfever, but you are more likely to have it if your parents do.
Some people do get symptoms later in life, with an increasing number of middle aged and elderly people being affected.
Sadly, there is no specific start and end date for hay fever. But the spring and summer seasons are especially bad. Weather conditions and pollen count vary from year to year, but with last years levels being among the highest in the last century, similar miseries can be expected this season.
Hay fever worst affects the young and active who are at work or school. According to Professor Stephen Durham of the Royal Brompton allergy clinic in London, the sickness can increase the chance of students summer exam grades being worse than previous out-of-season test results by 70%.
But bad news for the rest of you: studies show that adults in their 30s, 40s and 50s are increasingly at risk, so stock up on the tissues.
Those with other allergies, asthma or eczema, have a blood relative with these illnesses, and those who live or work in an environment that exposes them to allergens must be extra cautious, too.
There was an injection given to people in the 1980s to desensitise them to pollen, but it was discontinued after a number of deaths.
There are vaccinations now, and as research has developed there have been some suggestions for treatment. Key research in 2017 has shown that symptoms could be dramatically reduced in the long term if sufferers are exposed to controlled doses of pollen.
The treatment, a type of immunotherapy, involves exposing patients to increasing doses of pollen over time to build up their resistance. The pollen is administered either by injection or a daily tablet.
The trials 106 patients for the study by Royal Brompton's allergy clinic were split into three groups for treatment over two years.
One received injections, one daily tablets and one a placebo. The patients who took part in the trial all suffer from moderate to severe hay fever.
After two years of treatment, patients receiving injections and taking daily tablets reported a significant improvement in their symptoms and their quality of life. After another year, symptoms had returned to the same level as the placebo group.
Importantly previous studies from Royal Brompton hospital have shown that 3 years grass pollen vaccination, as opposed to 2 years, may additionally confer long-term benefits that last for for several years after stopping the treatment.
Prescription and over-the-counter hayfever tablets contain antihistamines.
Antihistamines get rid of histamines, the chemicals your immune system makes to rid your body of allergens.
If you buy normal tablets, from a high street store, you may think it's just a mild dose, but there's still a risk of overdosing.
Side effects are listed on the packaging so check before you take anything. They usually include blurred vision, headaches, sedation, enlarged pupils, restlessness, itching, dry mouth and ringing in your ears.
It's important to remember if you follow the instructions you will be fine. Check what other medication you are taking before taking hay fever tablets. Read the label and you will be fine.
Sadly, there is no way to prevent getting hay fever. But follow to these tips to avoid as much suffering as possible.
Most people get away with over-the-counter medications for mild symptoms. Nasal sprays, decongestants and antihistamines often do the trick. But if symptoms worsen, it is probably best to visit a doctor to ease you from the agony.
