What is the swelling around the left ear and inside the jaw?

Swelling sensation around the left ear and inside the jaw may be related to carotid body tumor, nasopharyngeal carcinoma, pleomorphic adenoma of parotid gland and other diseases.
1. Left carotid body tumor: this disease is a kind of chemoreceptor tumor, and painless lumps are often found at the angle of the jaw. With the gradual enlargement of the mass, other non-specific symptoms may appear, including: neck pain, localized pressure pain of the mass, hoarseness, as well as tinnitus, vertigo, blurred vision and other manifestations. If it occurs in the left side, it may feel swelling around the left ear and inside the jaw.
2. Left nasopharyngeal carcinoma: when nasopharyngeal carcinoma metastasizes through lymphatic metastasis, the cancer will first converge into the retropharyngeal lymph nodes located in the posterior pharyngeal space, and then inject into the lateral upper deep cervical lymph nodes, and in the case of left nasopharyngeal carcinoma, the lymph nodes will often be enlarged in the first place, and there will be a feeling of swelling around the left ear and in the lower jaw.
3. Left parotid pleomorphic adenoma: this is a benign tumor of parotid gland, with slow growth, often centered on the earlobe, smooth or nodular surface, clear boundaries, medium texture, activity and no adhesion. In the case of larger tumors, there is usually no other discomfort except for localized swelling sensation and surface deformity. If it occurs in the left dumbbell type, there may be a swelling sensation around the left ear and inside the jaw.
When there is a swelling sensation around the left ear and inside the jaw, you can actively consult a doctor for systematic examination in order to clarify the diagnosis and etiology, and regular treatment.
