I woke up for PT at 5 this morning and extended my foot and had a HUGE cramp in my right calf. It was the worst one Ive ever had. Yesterday was a 5 mile ruck march and today was just a pushup pyrimid to 15 and 16min straight ab exercises. Then 30-60's running. The whole two hours it felt like my leg was gonna fall off. Anyone have these before? Anything help them at all? AandF, I know you have, I watched as you had one durning Simpsons one day. Its 330 in the afternoon and I can still feel it a bit.
