How do I treat a bleb?

I stopped nursing my son about 6 weeks ago. Yesterday I noticed a painful burning sensation in the nipple area. Today I noticed that it was coming from a small white 'dot'. The pain is highly localized, and seems to come and go every few minutes. How do I treat it? Is this normal for a just-finished-nursing mom? Do I need antibiotics? How long will it take to clear up? Thank you!!

I don't think this is normal and happens to everybody. It didn't happen when I weaned my first baby. I found this information:

Plugged Nipple Pore (milk-filled blister) 鈥?This is often seen as a white "dot" on the nipple, usually at an opening of a milk duct. If is often shiny and smooth and exceedingly tender. Apply heat to the area and allow the baby to nurse or use a good-quality breast pump. Sometimes it needs to be opened by your physician/midwife with a sterile needle. @ http://www.macdonaldwomenshospital.org/D...

Since you are done nursing baby you can use a pump if this makes sense to you. Other reasons for sore breast include:

Plugged Ducts, Plugged Nipple Pore, Mastitis
Plugged Ducts 鈥?May be caused by incomplete emptying of the ducts during nursing. Usually this occurs in one breast. The area is tender, slightly warm and possibly reddened. There may be mild pain and the mother may run a slight fever (less than 100掳 F.) Place a warm, moist cloth to the area prior to nursing, massage the breast toward the nipple and nurse at least one feeding with the baby鈥檚 nose pointed toward the plugged duct.
Mastitis 鈥?This is an infectious process in which usually one breast is involved. It is red, hot and swollen. Mothers feel like they have the flu (chills, aching, vomiting) and often the fever is greater than 100掳 F. This is often caused by tight clothing/underwire bras, stress and fatigue, cracked nipples, plugged ducts, engorgement and a change in frequency of feedings. If this occurs, apply warm, moist heat, rest, take a mild pain reliever and call your doctor. Your doctor may want to prescribe an antibiotic, which you should take until all the pills are gone.

Nipple Thrush 鈥?This is a fungal (yeast) infection that can cause itching, burning nipples, peeling skin or patches on the areola, persistent sore/reddened nipples and a burning or shooting pain from the nipple into the breast. It usually occurs on both sides at the same time, especially after a mother or baby has been treated with antibiotics, or if the mother is diabetic. If this develops, call your doctor and your baby鈥檚 doctor for them to prescribe treatment. Both you and your baby must be treated, even if one of you doesn鈥檛 have symptoms.

I hope one of these options help you and further describe your symptoms. Definitely see a doctor soon if it doesn't go away. Good luck! and good for you for nursing :)
