A sprain/strain injury occurs when a ligament or tendon is stretched beyond its limits. These injuries may be treated initially for the first 48 hours with RICES: rest, ice, compression, elevation and support. Any increasing pain or discomfort lasting more than 24 hours is a warning that something needs to be checked and addressed.
Discs are the flexible cushions between the bones of our spine and depend upon normal position and movement of adjacent spinal bones to stay healthy. When a vertebra loses its normal motion, the healthy "pumping" of nutrients stops and the disc begins to dry, crack, and eventually bulge under stress, putting pressure on nearby spinal nerves, causing radiating pain into your legs or arms.
