Diagnosing sprains and strains

When diagnosing a sprain or strain, yourdoctor will ask how you injured yourself and examine the affected area. An X-ray may be needed in severe cases .

Your doctor will want to know about treatments you've already tried, as well as any medication you're currently taking that could affect the injury, such as Anticoagulant medicines (medication that reduces the blood's clotting ability).

Theaffected joint or muscle will be examined to assess the severity of your injury. Yourdoctor will check for:

• pain, discomfort and tenderness in the injured area
• swelling and inflammation
• any lumps and bumps not usually present
• bruising or bleeding in the joint or muscle

They'll also assess how much you can move the injured joint or muscle and whether you're able to put your weight on it.

If you have a severe sprain, your doctor may check whether the ligaments are loose. This is sometimes called joint instability, mechanical instability or ligamentous laxity.

X-rays

You won't usually need to have an X-ray if you have a sprain or strain unless:

• you're unable to put any weight on your ankle, foot or leg
• the bone is tender at specific points on your ankle, foot or leg
• you have difficulty moving your knee

An X-ray may also be recommendedif you're over 55 years of age and have injured your knee asyou're atincreased risk of bone fracture after this type of injury.
