I had a vacuum assisted breast biopsy on my left breast nearly 8 weeks ago, result came in 2 weeks later as above. It was a bit sore and I had a pulling sensation at that point but it settled down. Because there is a large area to take out and I have large breasts, I have elected to have surgery on both (melon) to attempt to keep them similar size/shape. This will happen in about 10 days and I am going for pre-med and discussion with the surgeon in three days. However, for nearly a week I have had a soreness under my armpit, I think I can feel a slight lump and I have a dull ache going down into my breast - a bit like mild toothache. If I take Ibuprofen it helps, there is no redness/fever or anything associated with infection and otherwise I am the same as normal except of course it is getting me down. I though it might be a lymph gland swelling so I read up on it and it says not to go to your GP unless it has been up for two weeks, and as I am seeing a specialist I thought I would leave it till I see her. Any ideas what this might be?
