Whats wrong with my nipples?

Hey,

My nipples have a yellow crust that sometimes itches…these pics are after the shower, so the crust isn’t hardened…but, has anyone ever dealt with this? I have been to the ER on several occasions…they gave me steroids, which cleared it up temporarily…but then it came back once I was done with the topical steroid. They gave me antibiotics, and that did nothing. I’ve been about 4 times…it originally started as a rash along my incisions…but that went away and then this came. I want to go back to the ER tomorrow. I had an appt with my ENDO…but, the topical gel had cleared it up, so I didn’t think I needed the appt. I should’ve have still went. Has anyone experienced this? This has been going on since about July/August. Thank you.
