Hi - just a note to say that it appears that my PT, which started after several hours in high winds, appears to be gone. It first started in April, reduced through the month of May, and has stopped. I've seen an ENT who confirmed a healthy ear and they did a hearing test. No further testing was suggested. I don't hear the PT anymore. Just writing this to share that it's possible for the PT to be temporary. I'm hoping it is gone for good, though I'm extra careful in weather now and realize that it's possible it would come back.
