My breast aches, as if it has has some pus in it. I don’t know what to do again, I have been on amoxicillin but I still have serious pains.
Have you just delivered a baby? Are you breast feeding? Does it feel like fluid? If it is actually pus then it is an infection most likely bacteria infection. . Also you will need incision and drainage with daily or alternate day dressing as appropriate.
You must also take note that degenerated lump can feel like liquid or thick pus. In this circumstances it is not usually painful. In this case antibiotics will not solve the problem but to do excisional biopsy.
You need to see a doctor for proper assessment
