A sprain is a stretching or tearing of ligaments — the tough bands of fibrous tissue that connect two bones together in Joints. The most common location for a sprain is in ankle.

Initial treatment includes rest, ice, compression and elevation. Mild sprains can be successfully treated at home. Severe sprains sometimes require surgery to repair torn ligaments.

The difference between a sprain and a strain is that a sprain injures the bands of tissue that connect two bones together, while a strain involves an injury to a muscle or to the band of tissue that attaches a muscle to a bone.

SYMPTOMS OF SPRAIN

Signs and symptoms will vary, depending on the severity of the injury, and may include:

• Pain
• Swelling
• Bruising
• Limited ability to move the affected joint
• Hearing or feeling a "pop" in your joint at the time of injury

CAUSES OF SPRAIN

A sprain occurs when you overextend or tear a ligament while severely stressing a joint. Sprains often occur in the following circumstances:

• Ankle — Walking or exercising on an uneven surface, landing awkwardly from a jump
• Knee — Pivoting during an athletic activity
• Wrist — Landing on an outstretched hand during a fall
• Thumb — Skiing injury or overextension when playing racquet sports, such as tennis

Children have areas of softer tissue, called growth plates, near the ends of their bones. The ligaments around a joint are often stronger than these growth plates, so children are more likely to experience a fracture than a sprain.

RISK FACTORS OF SPRAIN

Factors contributing to sprains include:

• Environmental conditions. Slippery or uneven surfaces can make you more prone to injury.
• Fatigue. Tired muscles are less likely to provide good support for your joints. When you're tired, you're also more likely to succumb to forces that could stress a joint.
• Poor equipment. Ill-fitting or poorly maintained footwear or other sporting equipment can contribute to your risk of a sprain.

PREVENTION OF SPRAIN

Regular stretching and strengthening exercises for sport, fitness or work activity, as part of an overall physical conditioning program, can help to minimize your risk of sprains. Try to be in shape to play your sport; don't play  sport to get in shape. If you have a physically demanding occupation, regular conditioning can help prevent injuries.

HOMEOPATHIC TREATMENT OF SPRAIN

Arnica  Used for any injury especially at the beginning stages where there is a lot of pain, bruising and swelling.  Immediately after injury, 

Ruta The number one remedy for sprains and strains (including carpal tunnel syndrome).   

Rhus tox  For a sprain or strain when pain and stiffness are worse on first movement, and symptoms feel better after moving around.  There may be restlessness particularly while trying to sleep.  

Ledum When injured area feels cold to touch and pain is better from cold applications.e.t.c
