I was browsing through this entire site and arrived at this question. There is the simplest of answers for this problem ... (unless it as an absolutely acute hearing problem.) The cure will cost you NOTHING and can be achieved in 30 seconds flat.(1) Stand.(2)Take a moment to calm yourself and take one or two very shallow breaths, breathing out completely each time (3) Then, on the last breath out hold and pinch your nose very tightly,( do not try to take another breath) and dance up and down or around, shaking your head very quickly from side to side. I guarantee you that in a few seconds you will have unblocked ears(unless you have an acute hearing problem ). This also works for your nasal passages.My friends...'look for the SIMPLE in medicine'.... People can rarely see what is in front of them and always remember that the body is it's own self-healing mechanism if only we would stop interfering!The body knows best , if only we would listen!
