I been playing for 20+ years , practicing seriously (4-6 hrs a day) for the last 10, I'm an Army band trumpeter. Anyway, I recently got what I believe is referred to as "embouchure overuse" or more specifically, I've come to a point where I can no longer play.
In hindsight, I believe this is the result of long practice days, and not enough rest. Even though I've been on this schedule for a long time with no problems, It's come to a head last week, and I found myself at the point at which I can no longer maintain an embouchure for more than 10-20 seconds. I have no pain, minimal swelling, just weak muscles, unable to maintain an embouchure. This was literally an overnight occurrence.
What is the "conventional" wisdom regarding this condition, as I've found no base of knowledge in the medical community here. Do I just lay off for a while? Go back to "basics"?
I'd like to recover as soon as possible obviously because this is how I make my living, but I am wary of the "too much too soon" approach. I've had vastly varying advice from a number of sources, so I'm interested in advice from people who are teachers, or professionals with first hand knowledge/experience.
Edit: In rereading my post, I've realized I did not relate clearly my specific question. I've read the past threads, particularly the responses by Rowuk. I understand the answer he gives. More specifically, should I start this rededication to better habits and better practice discipline immediately, or would it be more beneficial to take some time completely away from the horn before I do this.
