So right around one week and a half ago I was jumping rope and I felt that my left calf was kind of tight (almost like a constant small cramp) so I stopped. The next morning, I had difficulty walking on that same leg and it still had that annoying cramped feeling. After some research, I determined it to be a grade 1 calf strain , mainly because there was no bruising at any time. The cramp like pain got better gradually and today I feel like it is completely gone, but as I was just casually walking, I felt needle/stabbing like pains in the lower calf area (above the Achilles to about mid calf). I occasionally felt this pain when I had the cramps, but right now they are constant (ie: I can make them comeback every time by walking quickly, or they will comeback if I walk period). I'm not sure if this is a sign of recovery (normal feeling following recovery of calf strain) or a sign of a new injury(which is improbable because as this is the week of final exams and I've pretty much been home all week except going to school and coming back for the exam).
