If you have got rid of the lumps you might have avoided the full effects of mastitis before they developed. The first time I got mastitis I was kind of in this borderline state where I felt tired, achy, hot and terrible but each day I could mostly clear the blockage and be OK, but eventually it got much worse and I really had to have antibiotics. If you have been kind of borderline and gone the 'right' way - woo hoo!
