Hello, Thank you for asking your question at healthcare magic I understand your concern. There are few things that you can try to reopen the clogged duct -Take warm shower/apply warm compress on the affected breast -Try pumping milk from affected breast more -Massage the clog towards the nipple -Have your baby feed from affected breast first -Use Tylenol (if not allergic) for pain and discomfort Usually the clogged duct reopens and you will not have problems breast feeding However if the condition is persistent for a long time or if you develop severe pain, swelling and redness of breast,fever chills etc which are signs of infection, Immediately consult your doctor. Your will need antibiotics to clear the infection Hope I was able to help you. Please feel free to address any more concerns. Regards, Dr.Lekshmi
