Sports are a fantastic way of keeping our kids active, strong, and having fun. But what happens when that nagging ache continues to persist and your teen starts to complain of knee pain? 
 
You might ask yourself: Is this a normal part of youth sports? Will it go away with time? Should we rest it and if so, for how long? Do we pull our children out? When do I see a physiotherapist?

​A strain is a stretched or torn muscle or tendon. Tendons are tissues that connect muscle to bone. A strain occurs when a muscle is stretched beyond its limits during the course of everyday activities like with a sudden lift or a twist during sport or while performing a work task. Strains can happen suddenly or develop over time like in the case of repetitive strain. Back and hamstring muscle strains are common. Typically the local area is painful, swollen, red and bruised and the muscle may spasm and become weak.
