I had a milk bleb that would not budge for about 4 weeks, it finally went after putting lansinoh lanolin nipple cream on after every feed/pump and it softened the skin loads After a very warm shower the skin sort of exfoliated away when drying with a towel and the blockage came out xx
I tried every natural remedy when I got one but nothing worked and it became so painful, so I used a hot sterile pin and popped it, then used my electric pump to gently drain xx
Warm water and epsom salts in a haaka was the only thing which worked for me, had one for weeks but went in 3 days using the haaka
The thing that helped me was warm compresses on the nipple and it finally comes away with some gentle massaging. Other than that I just kept feeding baby off the good boob, and once semi satisfied (so they weren't starving and frustrated) and get baby to suckle on the blocked one which took a couple of days of being consistent. Keep going xx
