While many of us suffer seasonal allergies in the spring, some unfortunate people have to cope with the symptoms all year. Itchy eyes, rashes, hives, skin pimples, clogged sinuses, face problems, and frequent sneezing can be exhausting and frustrating, but this is a reality for some people.

Jon Bon Jovi, the rock star, suffers from hay fever to the point where he's had to leave the stage to cope with the bothersome and persistent symptoms. Ideally, someone with such severe hay fever should avoid spending too much time outside during certain periods of the year, but you don't have that luxury when thousands of people are dying to see you in a stadium concert in every city.

Some people manage their allergies by fully avoiding them, however, this can be difficult depending on the type of allergy. That would be nigh impossible for someone like Scarlett Johansson, for example. Because the actress is allergic to grass pollen, she must exercise caution while in contact with grass or grass-like vegetation. Even if you live in New York City, you'll come across the grass at some point, thus this is a difficult allergy to live with.

Scarlett's skin becomes irritated and scarlet rashes appear all over her when she comes into contact with grass. Her eyes become inflamed and tear up as well, so she should always have a few packets of antihistamines on hand.
