Don’t take a pain reliever before or during exercise or sports in hopes of preventing pain and improving performance. Some athletes and exercisers pop aspirin or other non-steroidal anti-inflammatory drugs before an event or workout in order to reduce inflammation and soreness and thus boost performance. This misuse can inhibit the body’s ability to adapt to challenging workouts and interfere with healing, besides increasing the risk of stomach bleeding and possibly cardiovascular problems. If you feel pain when exercising, your body is telling you to stop for a reason – and you don’t want to mask this warning sign. Of course, it’s okay to occasionally take pain relievers to treat soreness and other symptoms after exercising.
