My mom almost had to have ear tubes put in when she was in her thirties. The doctor told her to hold her nose and then gently try to blow air through her nose. This puts pressure on the ear and helps to force the fluid to drain. She said to do it several times a day.
It could be pressure from wax build up as well. If that is the case, you might also try a warm washcloth against the ear a couple times a day to help melt any wax in there. Also, you can irrigate the ear using an ear syringe and warm water with a little hyrdogen peroxide added to it.
If you have been congested at all, it might not be a problem with the ear yet. It could be sinus congestions putting pressure on the tube that runs to your ear. If this is the case, run a humidifier in your house or put a big pot of water on a low boil while you are at home. This will put steam into the air and help with sinus drainage. Also, using Vicks Vapor Rub at night can help with congestion and is safe. Benadryl can also help with sinus problems. It can help to shrink swelling in the nasal passages and help to drain congestion.
Most importantly, I would recommend calling the doctor soon. They may suggest you wait til next week or they may fit you in sooner just to make sure it is okay and not infected.
Good luck. Hope this helps.
