Sometimes, it's hard to acknowledge a problem before it's too late. If you have frequent or sharp pain in one specific area, you should address the problem before it becomes exacerbated and your recovery time gets longer. Visit Sports Medicine, if your team has access to it, or if not, visit your school's health center. Often, the solution will be rest and icing, but sometimes it can be an easy fix that you wouldn't recognize without a diagnosis: new running shoes, a simple sleeve for your knee, or even a back massage. If it's a deeper issue, then follow through with a recovery program, which might consist of strengthening exercises, stretches, and/or some kind of brace.
