My daughter plays the Clarinet.  She sometimes gets tired and she'll just take a break when she does.  She's first chair this year and going to Tri-state honor band at FSU next week.  I didn't have the heart to tell her she couldn't play.  Her surgeon said she could...just to take it slow after the surgery.  she knows her body and she paces herself.

My daughter plays the recorder at school and takes piano and voice lessons. Most of the time she is fine but she has had an an episode of weakness and tingling while playing recorder and once while holding a note during voice lessons. She rested, drank some water each time and was fine....though we always advise our medical team of what happenened.

All these activities - blowing up balloons, wind instruments etc lower the body's CO2 levels which reduces cerebral perfusion (brain blood flow), not a good thing when the blood flow is already compromised.  I guess everyone has to have their own risk/benefit view of things.  I don't know if the same things are a problem post successful surgery? My daughter has not had surgery yet.

Thank you all for responding.  Band is the one subject going well at school this year, so I think we will continue but tell her to take a break if she gets light headed, relax, have a drink of water and go on when she is ready!

Thanks
