Are these signs of infection after bilateral breast reduction?

Hello and thank you for your question.
It sounds like it could be from your menstrual cycle. To be sure, reach out to your surgeon for some clarification. Best wishes!

Dear Sincere9925,
the main symptoms of wound infection would be redness of your breast, increased temperature, pain. I understand your concern. However, without a proper assessment it would be difficult to determine what is wrong. It is best that you visit your plastic surgeon for further assessment. Only after thorough examination you can get proper recommendations and advice.

Hello, and thank you for your question. (Keep in mind that an in-person consultation is necessary for the best advice.) If it is a surgical site infection, it must be treated promptly. You should schedule an appointment with your plastic surgeon so that he/she can examine you, address your concerns, and (possibly) develop a plan of care. Best of luck!

You should speak with your surgeon and ask their advice.  Its impossible to answer your question without a formal examination.  Signs of infection can include fever, redness on the breast, temperature and an smelly discharge.  Discuss with your surgeon
