Ice the injury. Stay calm. Take over-the-counter (OTC) pain relievers. Focus on your breathing. Distract yourself. Visualize food.
For medical reasons explained in the next section, this is the first thing you should do after shutting a door on your hand. But, medical reasons aside, the cold from the ice will numb your hand if you keep it in place for long enough. Although the extreme cold will be uncomfortable or even painful at first, push through it and keep the ice in place. Eventually, you’ll feel less sensation — including pain — in the iced area. Your first impulse might be to panic, but try not to let yourself get overexcited. Excitement can lead to increased blood flow, which in turn might lead to harmful swelling. Furthermore, research has shown that anxiety leads to a heightened experience of pain, though this is more researched with chronic pain than with acute injury. Regardless, staying calm will help you stay focused and manage your pain in the short term. Although for severe injury, you should see a doctor who can both treat your hand and prescribe stronger pain relievers, for manageable situations, OTC medications will help you deal with pain. In general, OTC pain relievers are either acetaminophen (Tylenol, Panadol, etc.) or ibuprofen (Advil, Motrin, etc.).  Take all medications as directed. Acetaminophen should be taken every 4-6 hours, and ibuprofen every 6-8 hours. If you have stomach problems, kidney problems, or are pregnant, don’t take ibuprofen without consulting a doctor. People with liver disease should not take acetaminophen. Deep controlled breathing will help you calm down and lower your heart rate. Focus on the sensation of the air at every stage in the breathing process — how it feels as it enters through your nose, how it feels when you hold it in your chest, how it feels as it rushes back out through your nose or over your tongue. Think about those feelings, and nothing else.  Inhale slowly and deeply so your belly, rather than your chest, rises first. When you can’t take in any more air, hold your breath for several seconds. Exhale slowly and methodically, controlling the release of air rather than letting it all rush out on its own. When you’ve finished exhaling, pause for a few seconds before repeating the cycle with your next inhalation. Repeat this process until you feel comfortable releasing your attention. To take your mind off the unpleasant pains, try to let your mind wander to other stimuli that engage your senses. You might listen to your favorite album, watch an engaging TV show or movie, have a conversation with someone, or perform a light activity that doesn’t stress your hand, like going for a walk. Research show that engaging your five senses makes your experience of pain more manageable. Research shows that guided imagery, in which a person or audio recording helps a person in pain focus on relaxing mental images, can help ease both chronic and acute pain. However, a recent study suggests that simply visualizing your favorite foods on your own can achieve the same effect without the external aid or guide. Just fantasize about tucking into your favorite foods — whether it’s chocolate or a cheeseburger — in intense detail, imagining how it smells, tastes, and feels. Let those pleasant thoughts take over your mind and the pain will fall away.
