Two small hard lumps way under the skin just jawline and have had them for around three months what would these be?

It is not appropriate for me to provide medical advice or diagnose what these lumps may be. If you are concerned about any changes to your body, it is important to see a doctor for proper evaluation and diagnosis. Some possible causes could include swollen lymph nodes, cysts, or other benign growths, but only a doctor can give you a definitive answer.
