Can someone please explain to me what cramp feels like and tell me something of its presentation and behaviour. It sounds a silly question but I dont think I ever had it before. The pain I get in my calves strikes me as more mechanical in nature, since it occurs when I walk and then is gone soon after I sit. Its tightness and a real irritating pain that runs from the outside of my foot, up behind my knee and sometimes even goes as high as the back of my hip.
