I'm a relatively new runner, doing about 5k 3 times a week. After my midweek run I felt a tightness in my right calf - felt like it was about to cramp all the time - this continued until today when I ran again - a brilliant run in pouring rain - but now my calf is really quite painful when I walk or stretch - but OK when not moving about.
I simply don't know if this is just a twinge, a bit of stiffness, or an injury looming.
How do I tell the difference?
Any advice appreciated. Thanks!!
