Hi,
I just had this. After 2 general doctor visits I went to the chiropractor for something else, and mentioned my ears, she asked if she could try to help. Of course I said yes and one, two three, better. Tricks she taught me: gentle tugs on the ear, from the lower lobe tug down and out and from the top pull up and out while opening and closing the jaw. It really helped when the feeling started to come back. This mixed with the trick a wonderful flight attendant taught me have really saved me. Okay, this one sounds weird but did help me, especially on airplanes where the cabin pressure mixed with the ear pressure made me think my head would explode: take a short tea cup or small bowl, like the ones found on planes and put a napkin or paper towel at the bottom, pour boiling water on to the napkin and place the cup with the hot wet cloth up to the ear with the head sideways (so the hot water does not pour into the ear and down the face), create a seal with the cup flat on the side of the face, completely around the ear. Stay there for a while. The steam in the cup and the suction create a reverse release on the pressure in the ear. There is a fuller scientific reason this works, I don't understand it, nor do I need to. It has helped me out many times and I am grateful.
Remember to breath in and out, stress only makes everything look and feel worse. Assume the least not the worst, your kids have a cold, you got it and it settled in your ears. Try some of the advice given here and then if it is still bothering you before the weekend go to an Ear, Nose and Throat Doctor. Some things do clear up and others get worse if ignored. Remember, by taking care of yourself rather than ignoring it and hoping it will go away, you actually will be a better mother and wife, because if you are not well you can't fulfill your responsibilities to the best of your ability. By taking care of yourself and your body and soul, you are actually taking care of your family, giving them healthy you, not spinning, not feeling well you.
Good luck and feel better soon.
