Re: injury and cardio
No I havent been to the doctor …I figured it would heal in due time with rest and using knee supports. I felt more discomfort then pain so didnt think going to the doc was necessary since the knee is gradually getting better. I’m so bad about going to the doc (no time) 
I am not sure exactly how my knee got this way but I am almost positive that it happened during my cardio kickboxing class. I believe that when I was pivoting my knee went in one direction and the rest of the my body in the opposite. Instructor is guessing the same thing.
The discomfort is in my knee and goes down the the left side up to the shin…not sure if that makes sense.
I have been working out for several years now and this is my first injury…it’s minor but still a setback sigh
