To sum up, an upper neck problem affecting muscle tension of the throat and behind your jaw can make it difficult for the muscles of the eustachian tube to 'open' during a swallow or yawn. You can feel behind your jaw bone in front of your neck for pain. The side that is worse usually has more pain and tension.
Throat pain and a feeling in your throat with difficulty swallowing can be associated wtih this problem. Headaches and dizziness can also be related.
There is hope! Treatment is usually very successful in getting rid of these ear symptoms.
