does icing an injury slow healing
But now for the first time, researchers have found a hormone produced by inflamed tissue that could help heal damaged muscle. This discovery turns the conventional wisdom that swelling must be controlled to encourage healing, on itâs head. Putting ice on an injury may prevent healing according to scientists. And these findings could lead to new therapies for acute muscle injuries caused by trauma, chemicals, infections, freeze damage, and exposure to medications which cause muscle damage as a side effect.
