I'm growing concerned that I may have a more serious neck injury than I've previously been willing to admit to myself. I'm experiencing numbness/tingling in my right hand and fingers. It's pretty much constant, though it is triggered more severely by sitting or standing with good posture. When I slouch, look down, or particularly when I invert on to my neck from the guard, the symptoms are relieved. From what I have read this could be a brachial plexus injury or some type of disc problem in my cervical spine. Does anyone have any experience with this kind of thing?
