my boob looks really odd. What is it?

[AliGrylls]

Been bf'ing exclusively for 4 months.

I have just noticed that my boob looks really strange. It looks like a huge varicose vein. It is not painful / uncomfortable. Is it mastitis? How do I get rid of it? Want to resolve quickly because I hate the idea of having to give up bf'ing.

Give the health visitor or GP a call? Sounds bit worrying :(

Of course get it checked but it may well just be the breast feeding boob veiny thing. I remember passing a mirror getting out of the shower and realising I was doing a reasonable imitation of 7 of 9. They did all go back to normal eventually.
