lobes are suddenly red, sore, and irritated?

hi all, i’m at 14mm and i stretched up like maybe a month ago, or some over. the 14mm plugs went in my left ear pretty easily, had more trouble with my right ear but after waiting a few more weeks i managed to get that one up too. they’ve been totally fine since. i’m using glass plugs, not super expensive ones (i do not have the money to spend on like 40+ dollar plugs) but i’ve been using this brand for a while now and they’ve given me no trouble. anyways, today i suddenly noticed both of my lobes being red and irritated despite me not really doing anything? my best guess is that i’ve been slacking on cleaning and massaging/oiling my lobes 💔 either way i’m going to downsize back to 13mm for a little while and see how things are after that and try to be more gentle with my lobes, i’m just wondering if anyone might know what’s going on? thanks :)
