Re: Calf Strain
or simply doing ankle mobilization exercises while you're sitting or lying down.
eventually doing some mild massage / foam rolling when the pain subsides.
if you're able to walk on it without much discomfort, it's probably just a mild calf strain, and nothing like rest and mobilization exercises couldn't fix.
with regards to salt, if it was a severe cramp from electrolyte imbalance, salt would actually help.
