Very worried

Hey ladies,

Firstly I have not had any diagnosis of breast cancer just been I a whirlwind of doctor after doctor and no answers..

So I now have appointment for breast clinic Monday coming have had chest x-ray today to rule out other possible causes.
I have been dealing with very severe outer left breast pain for almost six weeks now shots of pain dart from the outside of my left breast to my nipple and then right to the centre of my chest I get a sudden stab of pain. I have been unable to even sweep a floor and feather like touch leaves me in tears. Infection has been ruled out. I initially went to my GP over a bulging vein in my left breast that only appeared when I lay down felt kind of silly for going bit now I am very glad I did. When she examined me I had little pain she explained she found what they call a mouse lump. She decided to do one last check and when applied pressure to the area I was suddenly in alot of pain. After I left the surgery the pain just shot out of nowhere absolutely crippling me for weeks now. My underarm is quite tender and all that general side of my breast and underarm is obviously swollen. I haven't been able to put on a bra for weeks and have to hold my breath through the really bad shots. I guess I'm writing here to see if anyone has experienced anything like this. Any advice would be very much welcomed. Thanks so much!
