Hello, I've been having a burning stinging pain on my left nipple that keeps coming back. It feels like a lump forming when it returns and it stings a lot or a burning feeling. I've had inverted nipples all my life and now my left one isn't. My GP referred me to the breast clinic where I had an ultrasound which didn't show a lump just some thickening which they said I should keep an eye on. I've had two lots of antibiotics now which works but unfortunately it keeps coming back. I am 36 years old and really need to find a solution to this and wondering if anyone had something similar. Thanks
