There are very few baseball players that would be telling the truth if their arm hurt. Especially among the high school and college level. For players at this level they are playing a four year long tryout in which they showcase what they have in hopes that somebody from the next level up likes what they see. And, naturally, during a tryout or a showcase, players are giving 100% because they cannot afford to give any less. No matter who you are your body needs rest and time for healing. Baseball players often do not get the rest that they need. But to say that they cannot play because their arm is in pain could end their chances. So more often than not baseball players are continually dealing with arm pains and simply pushing through it. How they do this is the part that starts to become really unhealthy. Some players prefer mental toughness and simply accept the pain and play anyways. Others get rid of the pain through various other means. For the professional players getting big paychecks this is not much a concern affording these things. High school and college players, on the other hand, often resort to cheaper alternatives such as ibuprofen. Ibuprofen has become the best friend of many a baseball player. The problem is that while they may not feel the pain at the time, ibuprofen allows the player to continue to cause harm without the warnings from the brain to stop. The other problem is that players start to build up an immunity, and this combined with increasing the harm done, more and more ibuprofen is need to lessen the pain. In the long run this is not healthy at all but most players are more concerned with the here and now and throwing one more hard fastball for a strike or making a clutch throw to the plate from deep outfield for an out.
