A bleb is a white (or clear, or yellow) spot or a blister on the surface of a nipple pore. There are 2 main reasons they can occur:
Blebs can cause a lot of pain but there are some treatments available.
It is important for a bleb to be treated effectively, as they can prevent good drainage of the breast and result in blocked ducts or mastitis. Your baby is the best treatment for a bleb! They will do the best job of draining the breast and in lots of cases, the suction they create while breastfeeding will pop the blister spontaneously.
Sometimes, your breast may need a bit more help to get rid of the blister.

If that bleb is persistent, your doctor may prescribe a topical steroid cream to address the inflammation. The ABM guidelines advises topical moderate potency steroid cream such as 0.1% triamcinolone.
It’s a good idea to keep feeding or pumping after a blister has popped to make sure the breast is well drained.
As we know these days, a blocked duct is actually caused by inflammation. That is the same for a bleb. So reducing inflammation may your best option to relieve the bleb. This may include:
When you have a bleb and blockage, you usually DON’T have a fever, or any other flu-like symptoms. The breast is not usually red, but it may be tender to touch and feel firm, possibly engorged. If the blockage doesn’t clear, this may lead to mastitis due to a build up of pressure in the breast tissue behind the blockage.
Even if your nipple bleb clears, then you come down with mastitis soon after, the bleb is likely the cause.
Prevention of blebs is always better the cure!!
