Hello there, I can understand your concern , I would like to know a few more details.. Does the swelling pains? Is the swelling hard or soft ? It could be a enlarged lymph node or an abscess . Is there any other swelling in other parts of your body like neck armpit etc.,in my opinion you should consult a general surgeon in person as a physical examination of such things can yield greater information as to what it is .get a complete blood count and absolute eosinophil count done and take the reports along. I hope I have answered your query. Best regards Dr.Anil Kumar Jain.
