I have heard that Iceing pulled muscles can promote scare tissue. Is this true?
We have not been able to locate any current research on the incidence of scar tissue production associated with topical ice application to soft tissue. Scar tissue is formed when the cumulative injury cycle is initiated. This cycle begins with some form of injury or trauma (acute or chronic) which produces inflammation and pain. The inelastic scar tissue matrix is formed over the areas of stress and injury. Since this tissue is resistant to stretch, normal movement patterns are commonly affected which produces continued inflammation and pain, and continues the cumulative injury cycle. Ice is often applied therapeutically to reduce inflammation and pain following acute or chronic injury. Early intervention and care of the tissue trauma will reduce the associated effects of the cumulative injury cycle.
