What Causes Numbness In Calf Muscle After An Injury?

Hello, I am a 19-year-old college student and a couple days ago I think I injured my calf muscle. I was stretching in dance and my calf down to my foot on the right side started to go numb and get a tingling sensation. I didn't feel any pain at all, just an uncomfortable numbness. It was still numb the next day so I went to my doctor and said they would do blood work to see what it is. Today I woke up and my calf muscle is extremely sore feeling, and the numbness is still there. What is going on?
