I've done a search in the forum for the answer to this problem but I seem to be alone with it so I'm asking it for myself! My problem started about 12 months ago, where occasionally I got pains in my head after playing certain high notes (D's, Eb's F's etc which I have been playing in the range of for ever). Gradually the problem has got worse and now I'm at the stage where it is EVERY time I play above even a top A I get severe pains in my head. I'm fairly certain my technique is sound because I'm blowing properly and have got proper support from my diaphragm and everything, but these pains are getting to be a bit of a concern. In the early days, the pain would only be there for the duration of the note or for perhaps a minute or so after, but more recently it's lasted much longer. I'm raising the question now because last night I played a couple of top C's (nothing spectacular) and the pain was incredible. It was still there this morning too, which is a first. It's not like a headache-type pain, although I do get a headache afterwards, and it is usually centered in the same place in my head. Has anyone else experienced this, or can anyone offer any advice please?
