Well, it's been fun, but I may be through with the martial arts. Two weeks ago I blew out my back and what the MRI showed wasn't good. I'm in pain and am losing feeling and strength in my right leg. The doctor said not to be stupid or things could get a lot worse. More pain, ...loss of function, ...incontinence ...Whoa! That last word really caught my attention. I really can't see myself teaching VT ...or doing my day job (teaching high school) supported on crutches, moaning in pain and wearing a big diaper. I did conduct class last night, but only SNT, some basic steps, punches and soft chi-sau. No kicks, bending, twisting or sudden, jerking movements of any kind. It's not good enough. Next week I have a consultation with a PT recommended to me by my spinal specialist, then a consultation with a neurosurgeon in about 6 weeks. I'm seriously depressed about this ...and on my way to becoming seriously broke, too. Wish me luck, guys.
