Ear plugged! Can t hear help pls?

So my ears tend to get dry a lot so I put oil in my right ear and ever since its been plugged. I think I might have put a bit too much so I went to the doctors and he cleaned it out with warm water and a tube thing. He got wax out of it and he said the water should dry in a few hours. It s been 2 days and it s still plugged. I blow with my nose closed and it opens but when I swallow it plugs again. What do I do to unplug it?theres no wax in it and I am pretty sure there s no water so please help. I can t hear too much out of it. But I can still hear a little. Any home remedies?

Thanks
