After 4 1/2 years of bf-ing, I weaned my DS in December. Beginning last night, I started to feel 'plugged up' in my right breast. Can one get mastitis after weaning? What can I do about it? I haven't been able to express in a while.
I had something similar happen four months after weaning. I did not need antibiotics and definitely did not try to express anything. I rested, took vitamin c, garlic, drank lots of water, and it went away. Good luck!
