Is it normal for my ear to do this?

Sometimes when I wake up, I would rub my ear because it itches and I think the earwax like bundles together and makes it so that I can't hear out of that ear. I don't know why but it only happens to my left ear. Most of the time when it does that, I rub it a few more times and then I can hear. The other times, my dad has to take like a little blue pump thing and squeeze some warm water in it and put it in my ear and squeeze. The fist time he did it, it worked. Today when I woke up, it happened again. I took a shower and I thought it helped until I got out of the shower. I'm thinking to boil some water, stick my head over the steam and hope that it works.
