so , did you ever have problems with the tubes, or were they always a success??
I had the procedure done today... All went well, Started with the the left ear, put some numbing stuff in there, it was supposed to burn but i had very little burning.. he did the cut, suctioned out some fluid and put the tube in.. the right ear was a little more painful while doing it, but again about 2 or 3 mins on each side, was def something i could handle... immediately both ears unblocked and i can hear everything fine now.. matter of fact im hearing noises that I forgot how they sounded... So all in all tubes worked out great, now I just hope it stays this way.
I can't help with your questions - my hearing losses are due to age. But I reply to wish you the best and to encourage you to trust yourself and your doctor, you will see/hear improvements.
The procedure is new to me, so I (and others I suspect) will benefit from you letting us know what you learn.
Good luck !
