I'm getting a shooting pain down the right side of my right boob extending almost into my armpit. It only happens during feeding and, to a lesser extent, expressing (using an electric double pump). It has been increasing in frequency and intensity over the last couple of days. I had thrush a few months ago and it definitely doesn't feel the same as that. No red patches, lumpiness that I can feel or tenderness.
Anyone know what it might be? Thanks!
