In my most recent dance class, 2 days ago, I was doing a hardcore pointe lesson. Whilst doing it I felt minimal pain, and didn't find it too difficult compared to usual. Yesterday, I woke up with a sort of tight, pulling pain from my mid inner calf, up to my knee which is still there today. I am finding it painful to walk and straighten my leg. As I have not experienced this before I was wondering whether anyone else had, and whether its anything to worry about??
