Betta injury or growth/tumor?

I was looking at my betta and saw this red injury/growth on the side of its head. It looks definitely swollen.

I am wondering if it’s an injury (there is a temporary diy divider in the tank while my female’s tank gets ready) and maybe he tried to stick his head in? Or does it look more like a tumor?

In either case, How should I treat him? 


Thank you very much for your time.

Maybe treat it with a little salt? Keep the water clean? To the best of my knowledge, you want to make sure it doesn't get infected. That may be as simple as watching it closely for it worsening or fungus growing on the area.
