Today I got the news that I have a lower back problem that is pinching or infringing on some nerves that leaves my right leg in an almost constant state of soreness and pain. The MD tells me that this is a chronic state that there is no "fix" for unless I have surgery (in his opinion that is an extreme circumstance and most with my problem do not have surgery, but it is a possibility). Now, as to my karate practice thus far, the only limitations I have noticed is that my front snap kick is bothered a little and my crescent kick (in my style it is called outside crescent but most others refer to it as an inside crescent) is greatly hindered, almost to the point that it hurts too much to throw it. Unfortunately, our outside crescent kick is featured in a few of our katas (my favorite thing), so I am concerned about the future of my karate practice. (Stretching my right leg is also greatly impeded, it hurts too much to do it.) I guess my question and the reason for this post is does anyone have any advice as to how I might cope with this situation and its potential impact on my karate future? From what the MD tells me, this situation will have exacerbations and "remissions" meaning it will come and go, but in general will probably get worse as I age (I am 40 now). Thanks in advance for any replies.
