Do normal people have balls on both sides of their chin?
Under normal circumstances, some people may feel a ball-like structure on either side of the jawline, which can vary depending on individual body constitution and typically does not cause any discomfort. If the presence of such a mass is accompanied by symptoms, it is not considered normal. Detailed analysis is as follows:

In healthy individuals, soft, painless lymph nodes can often be felt on both sides of the lower jaw—this is a normal physiological phenomenon. The submandibular gland may also be mistaken for a ball-like mass on either side of the chin; this is a normal glandular structure and usually does not cause pain or discomfort.
The presence of a ball-like mass on either side of the chin could also be related to swollen lymph nodes, which are often associated with symptoms. Bacterial infections in the oral cavity or throat may lead to enlargement of the lymph nodes in the submandibular region, presenting as firm lumps that are tender or painful.
If a noticeable lump appears on either side of the chin, it is recommended to first perform self-observation and assessment, paying attention to any abnormal signs such as pain, swelling, or progressive enlargement.
