Ulcer & Lumps On Fish’s Head?

Please help! We have had our betta for 2 months. Yesterday I noticed a couple of white spots and lumps on his head (but didn’t look like ich to me). Tonight after we got home, the fish had what looks like an open sore or ulcer above his eye. Smaller spots under his mouth.

The fish is still eating normally. The ammonia is <.02 ppm and ph is approx 6.2. I use Seachem Prime, AmGuard, & Stability, as well as Marineland’s EasyCare for ph and also API’s Proper pH 7.0 when needed.

Can someone please tell me what this is and how to treat it? Thanks in advance! Video link here (you can see it more clearly at the :28 second mark):
