Probably not wise.

You could just hurt yourself more and not be able to play sax for a longer period of time.

I was in a car accident that totaled both cars last saturday.

Felt okay that night, so I played some clarinet.

But then I took a few days off because of the whiplash and the second day feeling much worse.

A neckstrap sounded pretty painful, so I’m using my harness.

Today I practiced again for a little bit and it felt all right.  Didn’t sound so good though because I had missed a few days.

Hopefully the reed was partially to blame!

But really, you shouldn’t push yourself too hard.  Practice when you should.  Usually there isn’t a good excuse.

Occasionally there is.
