It didn't look like dried blood? (like from a popped pimple)
(And... just checking... did you swim anywhere with coral in it before your ears started itching?)
My own ears produce a lot of wax (I need to clean them twice a day). Especially if I don't, it gets so thick that the little hairs rip out / I'll get infected follicles/blackheads (aka somtimes the pimples will bleed... I know, fun)... in ADDITION to the canals becoming impacted with wax. If I skip a few days, it takes a few more for the buildup to be wholly taken care of. All of this is easily managed, however, by cleaning them twice daily. No impactions, no infected follicles, no hearing issues, etc. But sometimes a woman runs out of qtips! My ears have *always* been like this, however. ((I also have irritatingly acute hearing... I can hear dog whistles, have perfect pitch, teenager ringtones though I'm over 30, etc.)) If this is all 'new' for you, however... I'd definitely be trying to figure out an outside cause. (Ticks, coral, recent pregnancy/aka hormonal fluctuations, infection, etc.).
