Gary, Of course I can't know what your symptom is caused by, you might like to know that I frequently have a sense that my right ear is slightly plugged.

Also another hint I'll pass along: shortly after my treatments were finished I developed a fairly significant pain in my jaw on the left side (opposite of treated side) and I was seeing an oral sergeon (the reason I'll save for another post) He carefully listened to my story of symptoms and then simply said my pain was caused by over worked facial muscles. The fact that I was so stressed out by the pain I was feeling, I was moving my jaw around to see if the pain was getting worse. It was getting worse because I was straining my jaw muscles to see if I could still feel it! At first I didn't believe him, thought he was incompetent because he was too lazy to find the "real" cause of this pain....He was right....and I learned a very valuable lesson.
