Ok well my first injury. I know I did it during plyo legs, the pliee with dumbell I went to heavy and pulled a muscle but now for over a week it turned into a pinched nerve i can feel it in my neck around left shoulder under arm and down, my index finger is numb and tingly. I am not one to run to the dr but I have tried heating pad, hot shower, and massaging nothing working have any of you experienced this and will it go away on its own or should I break down and go its not painful anymore just annoying now.
