[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have some enlarged axillary lymph node or some other infection.  It may be due to vaccine or accidental infection. You should take a course of antibiotics. If it doesn't respond to treatment then biopsy diagnosis is advisable. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
