Yes. I too have been getting headaches- for about 24 hrs. after playing. That is why I joined this forum. I have played since Jr. High and am now 70 - stage band, brass quintet, trad. jazz band, church gospel band, and practice regularly. But I'm afraid I might have to give up my passion - trumpet playing. I don't want to have a stroke! I'm going to switch to one of my cornets and see if blowing less air is the answer.
