There are some small lumps on the left and right sides of the neck, the small ones are very small, and the big ones are the size of beans. About four in total. The doctor asked me to have a puncture biopsy. May I ask who has done the puncture and is it painful?

The lymphatic system is the body's defense against diseases. The symptoms of the ear you are talking about are likely to be an ear infection, which leads to swollen lymph nodes, or it may be a problem with the lymph itself. A puncture is similar to an injection, except that the needle is thicker and the neck is swollen. The nerves are more abundant and may be a little painful.
