For myself I am not a fan of icing for an injury as I have never felt it benefited me. The only time I use heat is mildly when in the shower as I doi not want to inflame. The body is smart and largely able to take care of itself. There is some scientific evidence that icing is actually bad for healing /swelling. As well as some people who claim to know better:
