WHY DOES IT HURT?
After a trauma (injury to the muscle and/or tendon and ligament tissues), the healing process for these tissues begins.
The first phase of this healing is inflammation (warmth, redness, oedema, pain). This painful phase consumes a lot of energy and causes heat.
Applying something cool to the area greatly slows inflammation and relieves the pain.
