The muscles in the right earlobe are tight and stiff. Sometimes I feel pain when I massage the right side of the jaw joint, and my symptoms will be much better. I have also been to the doctor many times, and I have been to the dental hospital for a checkup before, saying that it is a misshapen jaw, and I need to do orthodontics, but I have no results from the checkups, and I have checked the cervical spine, and I have done an EEG, and they are all fine, but every day is very uncomfortable, and my condition has been for ten years, and I would like to ask about my symptoms, and if there is a problem with the bite, it will cause these symptoms. I have been suffering from this condition for ten years. How should I treat it? Chen Qi, Department of Stomatology, The Third Affiliated Hospital of Sun Yat-sen University: Hello! Your problem is not necessarily caused by the cervical spine, but may be related to the right TMJ (located in front of the ear). The temporomandibular joint is one of the most delicate joints in the body and is easily affected by occlusal imbalance leading to lesions. The accompanying symptoms include headache and neck pain, and the symptoms of the joint itself are not obvious at a later stage, and the occurrence of bone resorption will lead to the jaw deviation you mentioned. We suggest that you go to the dentistry department to check the TMJ bilaterally, at least to rule out the cause. I hope this will help you and wish you a speedy recovery.
