Well, I took Jenn's advice and decided to try and mow the lawn, My calves were killing me but I forged on, I somehow managed to do it ( 1 hour ), After, I watched the Twiching storm in my feet,toes,calves for about an hour. Talk about ache!! Today my calves feel like they were beat with a baseball bat. Gotta love thgis BFS *beep*. ??? With a MND does exercise cause the muscles to twitch more??
