The telling characteristics of acute pain are that it is sharp and very localized. You can literally put your finger on acute pain. Acute pain comes from causes other than too much exercise, of course. Drop a frying pan on your toe, for example, and the pain you experience is acute pain. You know precisely where the pain is, and the message is unequivocal: Don't drop another one, or move your foot if you do. Likewise, the athlete who enters the realm of fourth-degree pain that is localized and sharp is in a good position to do something about it by changing routines, resting, and identifying and correcting biomechanical problems.
If acute pain is disregarded too long, though, you enter the realm of chronic pain, the treatment of which is much more complex and involved.
