A sprain is an injury involving a stretched or torn ligament (the tissue that connects two or more bones at a joint is stretched or torn).[1]

Signs and symptoms[edit | edit source]

  • pain
  • swelling
  • bruising
  • not being able to use the joint
  • you may feel a tear or pop in the joint as it happens
  • joints may then feel either stiff or unstable, more severe sprains may make it impossible to put weight on the joint because it is too unstable

Sprain grades[edit | edit source]

Grade I[edit | edit source]

A ligament is stretched or has a very mild tear, little or no instability at the joint.

Grade II[edit | edit source]

An incomplete (partial) tear in the ligament, with some looseness in the joint.

Grade III[edit | edit source]

A completely torn or ruptured ligament. This may feel like a broken bone since it’s often impossible to put weight on the joint or use the affected limb because the joint too unstable.[2]

Prevalence[edit | edit source]

Sprains commonly occur in the general population.

Symptom recognition[edit | edit source]

Sprains are not a diagnostic symptom of ME or CFS.[3][4][5][6]
