Yep, I have had these on and off in the past 2 years, though they seem to be forming quite regularly now. I also had septoplasty with turbinate reduction around 2 years ago also and also have significant GERD.

Do you have any more information on your cysts? What has the doctor said? Are you able to get rid of them with medication? I assume it's not cancerous?

Thanks for your time.

edit: Oh my god, I have seen the pictures posted in this thread and what I cough up looks exactly the same! There seems to be a lot of septoplasty and related surgeries amongst us all having this problem :/
