sounds like you are dehydrated. drink plenty of fluids. your muscles need water & fluids to help them work correctly.
what is causing the calf muscle pain that happens only when i stand up i am currently up to six days of watery diarrhea? . the pain is specifically in the posterior region of my calf. it started out at the top of my calf muscle and all the way down to my ankle. but currently it is at the inferior part of my leg and goes down to the top part of my ankle. it is like a throbbing pain as i stand up. it is like when the circulation comes back and it hurts. when i feel the area it hurts when i lay back down it doesn't hurt as much. this all started with my diarrhea.
