I noticed Saturday while doing a high impact cardio karate class that my right ham tightened up so bad I couldnt kick. The next day same calf was sore. Monday and Tuesday seemed pretty good but I woke up this morning with a dull ache in my Achilles. It doesnt look swollen but is very sore if i squeeze it just above where it attaches to the heel.
Is this a huge problem or just some sort of tendonitis like what i get in elbow a lot?
