Thrush seems to be an elusive problem with so many different symptoms including being asymptomatic - how do you know if you have it for sure? I have been having some breast tenderness after bf - and my let down is heavy and feels like pins and needles, but I also have brief pain on the left when she latches but it goes away pretty quickly - I assumed this is normal? Just today however I thought I noticed a white spot on her lower gums and our last bf was a struggle - she kept pulling off and crying but then would relatch quickly to just pull off and cry again. She latches and relatches quite frequently to begin with, but I also thought that could be because of the heavy letdown? I also had mastisis 2 weeks ago and took an antibiotic. Any thoughts??
