I would recommend a physician/dermatologist’s evaluation. Treatment depends on the confirmation of diagnosis. The other possibilities are of swollen lymph nodes, cysts, lipomas, boils, abscess or warts.

For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
