Eczema or thrush on nipples?

Anyone have this? I have very sensitive skin and currently have eczema all over my hands and arms... and I used to get this itchiness on my nipples but it would go away. Now I have it and I don’t know what to do.. it’s not flaky like eczema it’s more moist.. so maybe it’s thrush? What should I do to get rid of this or ease this? I don’t breastfeed but I’m sure thrush could come up from sweating or wearing a dirty bra
