Hi. About a week ago by tomorrow, I had crossed the street and avoided being hit by a car by suddenly jumping out of the way. My right leg calf tightened up. Stupidly, I did not think of applying a cold press as I had to take the subway to work. This whole past week, only my right leg calf still felt tight. After a night s sleep the swelling of my right calf would subside somewhat. I only thought of applying a cold compress four days ago. The cold compresses has eased the swelling intermittently and especially after a night s sleep. How long does this last ? Is this cludification? It s nit edema because it s only my right calf that swelled.
