Susan Findlay of the North London School of Sports Massage talks about the use of sports massage in treating calf strains.
A massage therapist can help with the treatment of a calf strain, by feeling which muscles are tight and flushing out waste products and breaking down adhesions. This should only be done after the acute phase has passed (2-7 days depending on severity).
Initially the treatment should be RICE. Frequency of massage treatments depends on the severity of the injury. A mild strain may be ok with a couple of sessions. More severe injuries may take longer.
