Can someone identify this white protrusion on my tinfoil barb?

My discus get them from time to time shortly after I feed blood worms.
Prazipro tends to kill most of the worms after a dose or two, but the fish don't always survive the treatment.

The white bump gets bigger then pops after a few days and then a hole is left.
It then slowly heals after a few weeks.
You may then need to treat with Furan 2 for the hole in the side.
