About a month ago I slept on my side as I normally do, with my left ear to the pillow. The following morning I woke up and my left ear felt very plugged (hearing was muffled), and it would pop occasionally, about every half hour or so, only to return to it's plugged state. A week later the symptoms changed to just a constant plugged feeling, rarely popping. I get rushing and pounding sensations often, and my hearing has significantly decreased in my left ear. A week into the problems, my ear also began "leaking" it seemed, an earwax-like fluid. Recently it has turned into pure blood. This morning it took me approximately 20 full Q-tips to completely clean it out, and I feel like more blood flows into it throughout the day. What could this be?

Time to go to the doctor, blood from ear can't be good.

It could be a perforated ear drum?? But yes go to the doctor!
