I didn't want to hijack another thread but the topic on the other thread about tension, buzz and using the upper diagonal muscle got me to do a bit of thinking. I am a Sleep Apnea patent and have been one for at least 10 years. I have frequent sinus infections many times I believe due to my equipment (c-pap machine) which has air pressure applied through your nose from a machine through a mask and hose that must be kept clean and often times replaced to prevent infections. My luck hasn't been good. I also have had sinus surgery as well as a bout with Bells Palsy. I am not sure if there is a connection to these events or not however the purpose of this thread and the reason I am writing is that I have noticed that my upper diagonal muscles are sometimes weak because I have had the mask fastened on my face all night as I sleep. If I have sinus issues I sometimes pull the straps tighter so air doesn't go out the sides but rather into my nasal passage ways. I think I have dropped a few notes in range and maybe a bit of control because of this issue. Would the Doctors on here agree with this? What would you suggest I do to combat the weakening of this muscle group? Finally any other Sleep apnea trumpet players out there? What has been your experience? Any insight?
