I have a problem with popping/grinding joints. Especially when I'm doing bokken cuts, and even when striking or punching, I find that my elbows and shoulders will grind, and it is quite painful. I have seen many posts concerning popping joints, and often the assertion is that this will go away given time. Over what period of time do you think this would be, and is there anything that I can do to speed up the process? I stretch my shoulders (which are the biggest problem of the two joints) daily, and lift weights to strengthen them, but this hasn't helped. Any advice would be appreciated . . .
