Most sports injuries caused by overuse can be treated at home with RICE therapy. REST is very important. Avoid activities that cause pain or swelling to your injury. Pay attention to aches and pains. Exercising before an injury has healed may worsen the injury and increase the chance of re-injury.
Rest is needed for repair.
Rest an injury until it no longer hurts. ICE is the most effective, safest, and cheapest first aid treatment for injuries. Apply ice as soon as possible. Applying ice relieves the pain, slows the blood flow to the injury, and reduces the swelling. Ice also speeds the repair process.
