My boyfriend had given me a love bite on my right breast. After that my right breast is panning a lot even if I touch it by mistake or even if I don't touch it. What shall I do please help me out...

I don't understand the word "panning a lot". Do you mean "paining a lot"?
Sounds like it's bruised badly. You might try some BenGay on it, or maybe even some Blu Emu. That might help take away some of the pain, if you mean pain. If it doesn't stop hurting in about 3 days, I would see a doctor. I do wish you the best, and good luck.
PS; Tell your boyfriend to take it easy!

So did he break the skin or just bruise you?

Broke the skin

Perhaps you got an infection... the human mouth has all sorts of nasty bacteria in it and a bite is one of the worst things you can get. I think it's time to see a doctor in case it is something that will turn serious.

Also, really now... a "love bite" that breaks the skin? That's a little extreme, don't you think?
