I was a competitive swimmer for 6+ years and play bass trombone in a number of music groups/orchestras, big bands and other smaller groups. I have been active my whole adult life. I developed multiple sinus infections and was diagnosed with asthma four years ago. I've had allergies and postnasal drip combined with reflux off and on.
I am now on medications but still suffer from seasonal and environmental flareups. It has severely limited my swimming due to sensitivity to chlorine.
Probably due to the horn playing and swimming, my peak flow is easily 800, with minimal effort. When I'm having a flareup, at worst, it would be in the low 500's. Is there a better way to measure my best peak flow? Has anyone had similar problems?
