I'm 3 weeks post pardum, I had the swelling appear in October last year and put it down to pregnancy. But now my boobs have settled down and I'm not breast feeding yet its still quite swollen? It does hurt sometimes and it's more pronounced than my other one. You cannot feel the lymph nodes. It's simply just a swelling but since prodding hurts alot more. I have saw a doctor when the baby was a week old and she said it's my hormones and nothing sinister and it's breast axillary tissue. Yet I'm still concerned as its not the same on the other side and it appears bigger. I haven't been referred or anything. I have got two photos too and you can see a difference. I also have health anxiety which doesn't help!
