I have a reoccurring pain in my calf muscle . First time it happened I was walking down the stairs. The pain was intense and didn't go away for two weeks or so. Then it happened again about a week or two later same thing walking down the stairs step on to left foot intense pain. This time the pain lasted about 3 weeks and slowly went away. tonight I was playing hotscotch with my kids and I hopped on my left leg and again it is trobbing, hurts to touch my calf.
