yellow nipple discharge(?)

i have a lot of eczema on my body especially in very moist or clothed areas (nipples, under my knees, inner thighs, elbows, fingers etc) and my nipples have been especially bad lately, and yesterday i scratched them too hard and they became a little bloody and irritated!!! i put some paper towel in my bra for about 5 ish hours and this was what i saw? please excuse my gross nails lol.. it’s warmer where i am atm and i was wearing a bra for school. is this normal and just a reaction to the itching? im not sure if its ACTUALLY discharge because it seems to be coming from the irritated areas on the areola rather the actual nipple
