Pain and redness but not an infection? 8 months after reduction (Photo)

’ 8mpo has been smooth until last week! I have pain in my left breast and it is redIwent to see my PS last week and she put me on antibiotics (JIC, she doesn’t think it’s an infection bc it’s not hot, I don’t feel I’ll etc) **she said I likely popped an internal stitch and sometimes it will take a while to heal** I’m on day 5 on antibiotics. And I do have a lot less pain, but if I’m super active during the day, my breast gets sore/swollen/red in PM. Wondering how long this will last.
