Lanwmover Blenny Swollen Head (Left Side) - Pls ID

[AJtheReefer]

While performing my weekly tank clean up. I noticed my lawnmower with the left side of his head swollen. What could this be? Parasit, lymphocystis, bacterial?

Here are some pictures. What should I do?

Rocky has been living in this tank for almost two years.

The condition appears to be getting worse. Any help in the ID of condition would be greatly appreciated

Will perform a large water change this weekend. Hoping that would help.

I have spent many hours searching other threads to see if there is something similar that would help me ID the condition, but no luck

I'm leaning toward lymphocystis. . .

Could this be popeye?

I was just reading the Conscientious Marine Aquarist book. . .
"Popeye . . . . swelling behind or in the eye. . .If unilateral (only one eye involved), the cause may be mechanical injury, such as the fish bumping into something. . ."

it does look like popeye as it says it is only 1 side.

i would watch for signs of bacterial infection. ie fin rot cloudy eyes.

do the water change good water quality is essential for popeye to heal.
