I experience the blocking of both ears whenever I exert myself such as by climbing a hill/stairs or playing tennis. I feel like I'm under water, can't hear properly and speak as if I have a heavy cold. It first happened 18 years ago, when I was pregnant, and I put it down to low blood pressure. I don't have a cold, or sinus trouble or wax blocked ears. Some people say its due to the change in season (it's now Autumn) but it has happened in spring, Summer also. I do occasionally clench or grind my teeth, and my jaw clicks when I open and close it (dont know if that's relevant, but I read it in some other answers) I've mentioned it to my G.P. who is as mystified as myself and hasn't offered any solution,

You have asked this question three times. It has been answered here

I suggested you get a referral to an ear, nose and throat specialist.
