Do Not give up. Last June I too had a lump in my right breast. I also had the terrible burning and pain.
I went to my gynecologist and she ordered a mammagram. It showed nothing. I asked her to order a sonogram, but she said she saw no reason to.
Two days I went to a nurse practioner not too far from my home. She felt the lump and instantly ordered a sonogram. She called me the next day with an appointment with a surgeon.
He took the lump out. It was a fatty tumor which was not malignant. It was wrapped around some nerves which caused the burning.
You go to another physician. I don't know if you have had a mammagram or not. I do not trust them any more. Tell your physician to order a sonogram of your breast. I know from experience that you have to be persistant. It is your body!!!
Let me know how you come out. By the way, I have NO MORE PAIN in this breast!!!
Blessings,
Ann
