Sport injuries can affect almost any part of the body, including the muscles, bones, joints and connective tissues (tendons and ligaments).
Sprains and strains are the most common type of sports injury. The difference between a strain and a sprain is that a:
Symptoms of a sprain or strain can include pain, swelling, bruising and tenderness around a joint or in a muscle. You may also find it difficult to move the affected body part.

Back pain is often felt as soreness, tension or stiffness in the lower back, but it can be felt anywhere from the neck and shoulders down to the buttocks and legs.
Repetitive activity or a heavy impact while playing sport can injure bones, causing:
A broken bone may cause swelling, significant bruising and tenderness around the injured area, and bleeding if the bone has broken the skin (an open fracture). It's unlikely you'll be able to use the affected limb.
The pain associated with a broken bone can be severe and make you feel faint, dizzy and sick.
If any part of your body looks deformed, including your fingers, you may have broken a bone. You should go to your nearest accident and emergency (A&E) department.

Hamstring injuries are tears to the tendons or large muscles at the back of the thighs. They're a common injury in athletes and recreational exercisers.
Sudden lunging, running or jumping can cause the hamstring tendons or muscles to tear, which can be felt or heard as a pop and will be immediately painful. The muscle will spasm (seize up) and feel tight and tender. In some cases, there may also be swelling and bruising.
Go to your nearest accident and emergency (A&E) department or call 999 and ask for an ambulance if you develop any symptoms of a severe head injury, such as:

Heel pain can occur when the thick band of tissue that runs under the sole of the foot becomes inflamed. It's a common running injury.
It can cause a sharp and often severe pain when you place weight on your heel. In most cases, only one heel is affected, although some people have pain in both heels.
Heel pain and stiffness can also sometimes be caused by damage or tightness of the Achilles tendon, which runs up the back of the heel. This can occur gradually over a long period of time, or the tendon can suddenly rupture or tear.
If you experience sudden and severe pain in the back of your heel, which may be accompanied by a "popping" or "snapping" sound, you may have torn your Achilles tendon and should go to your nearest accident and emergency (A&E) department immediately.
Swollen joints can be caused by conditions that affect the joints or structures around joints, such as bursa and tendons. Bursa are small fluid-filled sacs underneath the skin, found over the joints and between tendons and bones.
Examples of these types of conditions include:
Tennis elbow is inflammation of the muscles and tendons around the elbow joint. It affects the outside of the elbow and is usually caused by repetitive movement of the muscles in the lower arm. Golfer’s elbow is similar, but the inflammation occurs on the inside of the elbow.
Sudden knee pain is common in contact sports, particularly those that involve twisting. It's usually caused by a sprain, strain or tendonitis.
Other knee injuries include:
The ACL is one of four knee ligaments. It can tear if you stop or change direction suddenly, or if you land awkwardly from a jump. If you tear your ACL, you may hear a pop or crack at the time of the injury.
Other symptoms of a torn ACL include:

Shoulder pain is common in sports that involve bowling or throwing, such as cricket or baseball. Tendons around the shoulder (the rotor cuff) can become inflamed (tendonitis) or torn, causing pain.
A dislocated shoulder may be caused by a heavy fall or sudden impact. The upper arm painfully "pops" out of the shoulder joint and you won't be able to move your arm.
Go to your nearest A&E department if you think you've dislocated your shoulder. Supporting your arm with a sling while you make your way there may help reduce the pain.
Rubbing or chafing of skin can be caused by poorly fitting shoes or clothes. Make sure your sports gear is appropriate for your activity to help prevent chafing.
Get medical advice as soon as possible if you have a severe skin injury, such as a deep cut that won't stop bleeding. You may need treatment to stop the bleeding and stitches to close the wound.
