I've done it before...more than I should admit, really. After three years of drum corps, you tend to develop a tolerance to pain/discomfort that's unhealthy. I can't tell you how many times I heard people being asked, "Are you hurt, or hurting?" if they tried to sit out. No one ever asked me that. I never missed a rep in 3 summers. If you're not familiar with drum corps, think marching band but with all the athleticism of any sport. I ran more when I marched with Jersey Surf than I did when I played field hockey in high school. Check it out on www.dci.org.
Naturally, my experience there has carried over to practicing in general- you think, "I just have to push through a few more minutes..." Then a few more minutes pass, and soon you've pushed yourself too far. I nearly did this tonight; I was playing a right hand study from the Opperman daily studies and my right wrist kept popping weirdly, and I thought, "Just a little more..." I had to make myself stop and go home. No point in practicing technique when it's just going to hurt me.
As I mentioned in my last post, I'm currently working the kind of manual labor job that I've always dreaded. Being a pianist/clarinetist my entire life, it's not like my wrists had never hurt, but starting a few weeks ago, my left hand started feeling asleep and both wrists have had a dull pain that doesn't really go away. I've always been terrified of carpal tunnel, but now it seems to be a legitimate threat. I'm going to the doctor to get it checked out tomorrow, but even if she says it's likely carpal tunnel, I have no choice but to carry on at my job. In the mean time, I've purchased this book, at the suggestion of a fellow blogger/musician on Twitter.
As far as treatment, I had been using heat to try to relax my wrists, but with limited success. Tonight, I finally iced them and it actually seems to be helping. Also, I'm planning on restructuring my days- my daily ritual has been work 9:30-6, make dinner, go practice. I'm going to start waking up at 7 to practice in the morning, then my body can have all evening to recover. We'll see how all this works, and what my doctor has to say tomorrow.
