Pour a cup or so of salt into a pan and heat it up until it's very hot, just short of hot enough to burn you. Then pour it into a sock, and put that sock inside another sock, tie the end of the sock closed, and hold it against your ear. The heat soothes and the hot salt attracts moisture enough to get things moving around in there.
Be careful not to burn yourself. I had my brother do this for an earache, and he made the salt too hot, and (OK, why?) left it on his ear even though it was so hot it burned him. That was, of course, my fault.
For some reason, it hadn't occurred to me to warn him that if you smell scorched flesh, don't leave the sock on your ear.
ETA - Also you could try (first, because it's easier) lying on your back on the bed and then hang your head over the side. That causes a pressure change and sometimes that's all you need.
