Can anyone recommend an over the counter medicine that can get rid of congestion in my ear?

You can try irrigating your sinuses. Get a cup of warm salt water (like 1 tsp salt/cup), and you can either snort it and let it sit for a couple minutes to break everything up, then blow it out, or if you have a bulb syringe, you can shoot it up one nostril while bending over the sink with your head tilted sideways, and it should come out the other nostril along with all the crap that's up there. It's extremely unpleasant, but it works.

Get some vicks vapo rub. Take a large bowl and fill it with boiling hot water. Add a laerge spoon full of vicks.

Cover it with a towel. Duck your head under and breath in the fumes, but please CLOSE YOUR EYES. Breathing in deeply for about 10 minutes should help break up the congestion.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
