jazz9, usually overworking the chops occurs preparing for an audition or an important something or other. If you are overworked, you must not over due it. Practise in 30 min sessions with at least an hrs. rest in between. You must give up excessive pressure, and be kind to your chops. If you are indeed overworked and continue to push harder, you will get in trouble. If you take it easy, rest when you need to. Quit mashing that horn into your face and treat your chops good. You should recover quickly. You must still be in High School. Your age should help you recover. Use your brain as well. You could be at a fork in the road. Choose the right path and all will be well. Excessive pressure and brawn with out brain leads to the dark side. Remember, a hard session here and there, probably won't hurt you. But if you continue to beat your self up with excessive pressure and constant abuse, something has to give. Soft practise helped me recover. I still played several hard gigs during my recovery. But other wise treated my chops with respect. It took about 3-4 weeks to feel like my old self again. Good luck. If you want to make Trumpet a part of your future, and it sounds like you do. Take care of your embouchure. You need it for life.
