Dr. Hogan Shy answered
Lump: Depending on the size and firmness it also could be a lipoma or cyst. I would monitor the lump, if it is increasing in size, firm, and immobile I would recommend followup. Lymph nodes less than 1 cm are generally benign but if persistent or increasing, it would be reasonable consider biopsy. A flu shot does stimulate an immune response so some inflammation to a lymph node is possible.
