Last year before I fell pregnant I was diagnosed with a sebaceous cyst in my left nipple, about the size of a grain of rice. It did not hurt at all.

Recently I have started leaking colostrum, and now this cyst has gotten heaps bigger (about the size of a five cent coin) and is hot / burny and tingly. Is this a problem, or is it just colostrum forming?

Not sure if this thread is in the right place...
