says the bottom bulb’s full blown,
calls it bun. It’s ancient. Only a few
months ago my neurologist showed me

scans of my sinus cavity,
the sphere of fluid nestled there, probably
not growing. This was the not-

dangerous cyst. He said sensitive,
overactive, any pain, lots of headaches?
I told him no before remembering

rising in airplanes, how
the top of my nose and my eyebrows
feel like a tightened metal rod.

And every time in diving wells I stop myself
suspended under pounds of water:
Don’t hit the bottom. That cavity thrums.
