Hello dear user! I have gone through your query and understood your concerns! Thank you for sharing them on healthcaremagic. I think that is not an abscess. If it was that, you would on fevers all the time. It would require surgical drainage to be healed. Since you have not fevers, it is not likely to be an abscess. It might be a milk cyst, which are often during breastfeeding. It generally is self healed by the days. If it remains for a long time and causes you pain or other problems, please consult a doctor to see it from a closer view. I hope this answer was helpful to you! Please kindly rate it as helpful and write a short review about your experience with me! I would appreciate that a lot. Thank you and best regards! DR ERIOL.
