Hello Ginger1 and thanks for posting, 

I am not sure if this is normal in as much as I don't know how often nipple hypersensitivity is reported after a lumpectomy, but numbness and pins and needles can occur so I expect this is something that can happen because nerves have been disturbed during surgery and in hypersensitivity could be more excitable as a result. So it should improve over time, but I can appreciate that for now it isn't very pleasant to have to put up with it.  Do run this past your surgical team/breast care nurse when you have the chance and see what they say. 

If no one else posts with a similar experience here,  you could try the forum at Breast Cancer Now.

I hope things improve soon.

Give us a call if you want to talk anything over. Our number is Freephone 0808 800 4040 and we are around from 9-5, weekdays.

Best wishes,

Julia
