I'm attempting this exercise, and ATM it appears to be working, though I can see why.
My popping started happening about 1 1/2 years ago. It was during a stressful time in my life and I had idea what going on.
I thought I only had an ear infection. Well after seeing a chiropractor, ENT, family doctor, TMJ specialist, and a physical therapist I think I've narrowed it down as to what it might be. I hope this helps.
Out of all of the people I saw the only one that managed to do anything for me was the physical therapist. She helped lead me to believe that it was muscle related. There's a muscle in everyone's neck that runs right around the Eustachian tube area. She believed that it was enlarged or over used. We did many treatments of massage and it all seemed to work but the trick is that not only do you have to try and stop this muscle from being overworked; you have to strengthen the muscle that is being under worked in the first place. She gave me many exercises with a ball that I was doing and they helped but this tongue exercise seems to target this area just as well if not better.
So what caused this to begin with? My therapist and now I seem to think posture may have something to do with it. In that year and a half span I had started a new job. At this job I sit terribly typing all day at a computer. Apparently the wrong muscle tried to compensate for my terrible posture and it caused this side affect. This tongue exercise seems to strengthen the correct muscle helping ease the stress on the other. Thanks. If you have any more questions let me know. I hope this works as it seems to be working for me!
