One ear muffled hearing. Damage?

I want to know if I am affected by the Reiter's Ear Kiss condition. Someone kissed my right ear two days ago and the suction caused a sharp ringing (1-2 seconds) that sounded between a microphone feedback and something spinning very fast. No abnormalities and no pain is experienced later. But because I was worried I have been testing my ears and my right ear is very noticeably weaker - softer, muffled/covered, "protected" from high frequency sounds. There is a very subtle cotton like feeling in the ear but that could be my own bias. Having said that, my right ear was always weaker because 1) I had a right canal clearing minor surgery at 5 years old, 2) during flights only my right ear has significant pain, 3) I always suspected my right ear was weak from everyday music listening. I want to know 1) If this is anything serious - does the 1-2 second sharp ringing indicate any permanent or irreversible damage? 2) Do I need urgent checkup or can I just visit a doctor whenever I am free.
