Doctors often prescribe aspirin and nonsteroidal medicines to people who suffer pain from surgery and injury, but they do not help you recover faster from muscle injuries (1,2,3) , broken bones, joint damage, surgery including joint replacement (12) or muscle soreness after hard exercise (4)/ and they can cause diarrhea, belly pain and bleeding.
Nonsteroidals include aspirin, diclofenac, Anaprox, Lodine, Meclomen, Motrin, Nalfon, Naprosyn, Ponstel, Relafen, Toradol, Tolectin, Indocin and ibuprofen. They block prostaglandins that cause pain, but are also the first step in healing, so several papers show that what you gain in pain control, you may lose in actually delaying healing (6,7). Continued use of nonsteroidals delays bone healing (8), and taken over several months, they can increase the rate of cartilaginous breakdown in joints of people who have osteoarthritis (9,10,11).
Taking aspirin or nonsteroidals before an athletic competition can help you to compete more effectively by preventing soreness during exercise and they do not hinder strength, speed, endurance or coordination (5), but taking nonsteroidals before every workout can delay recovery and increase your chances of injuring yourself by preventing clotting and increasing bleeding. Nonsteroidals block pain, but they may delay healing.
