If you have horrible allergies, try to stay away from people. This is a good method for two reasons. One: people are obviously causing your allergies, so you should stay away from them as much as possible. Two: people don't like it when you're coughing, sneezing, or barfing on their neck, so get the heck out of their face. - James K. Wallace- Biologist, University of Austin
The best and most sensible, thing to do when you have allergies is to visit your doctor and alert them. Your doctor will chart the way forward and advice you on how to prevent and deal with attacks when they occur. He/she may also prescribe medication for the attacks.
