Icing injuries may slow recovery and prolong pain, study finds (opens in new tab)

Icing a sprained ankle or sore muscle, long used to reduce pain and swelling, may in the longer run delay recovery and prolong pain, new research suggests. In a preclinical study published in Anesthesiology, McGill University researchers found that even though cryotherapy (icing) eased pain in the short term, recovery time was more than doubled in some cases.
