If you have any fluid in your inner ear you could experience Virtigo. Sounds like you could have a slight inner ear infection. Might want to get a round of antibiotics if you start feeling any sign of pain. I grew up with my right ear getting inner infections at least 4 times a year and still get them once and a while. It doesn’t really restrict my diving but the more I dive the less ear infections I have because the equalization helps keep my Eustachian tubes clear and stretched out. Yours might not be cleared of all the fluid and you could try an decongestant or a decongestant and antihistamine together. Just follow the labels instructions.
