Sports Injuries

Exercising is good for you, but sometimes you can injure yourself when you play sports or exercise. Accidents, poor training practices, or improper gear can cause them. Some people get hurt because they are not in shape. Not warming up or stretching enough can also lead to injuries.

The most common sports injuries are

  • Sprains and strains
  • Knee injuries
  • Swollen muscles
  • Achilles tendon injuries
  • Pain along the shin bone
  • Rotator cuff injuries
  • Fractures
  • Dislocations

If you get hurt, stop playing. Continuing to play or exercise can cause more harm. Treatment often begins with the RICE (Rest, Ice, Compression, and Elevation) method to relieve pain, reduce swelling, and speed healing. Other possible treatments include pain relievers, keeping the injured area from moving, rehabilitation, and sometimes surgery.

Sports Safety

Playing sports can be fun, but it can also be dangerous if you are not careful. You can help prevent injuries by

  • Getting a physical to make sure you are healthy before you start playing your sport
  • Wearing the right shoes, gear, and equipment
  • Drinking lots of water
  • Warming up and stretching

If you have already hurt yourself playing a sport, make sure you recover completely before you start up again. If possible, protect the injured part of your body with padding, a brace, or special equipment. When you do start playing again, start slowly.
