My little man has (inflamed lymph nodes?) Behind his ears and flaky, itchy spots all over his body. I imagine they're itchy because he has a large bald spot on his chin, chest, and underarms.

Is it correct to assume he has a dual ear infection and possible fungal infection?

I've been keeping track of this issue for the past 2 or so weeks, but he has not improved. Aside from that he eats/drinks/goes to the bathroom normally.

Any advice?
