Hiya, could anyone give me a bit of advice please? I had a red warm patch on my breast around the time of my last period. My whole breast was so tender I couldnt examin it to see if there was also a lump- it was probably there for about 2 weeks. I visited my gp, the redness had gone by this point but she could feel a lumpy area where the patch had been. Ive got an appointment at the breast clinic next week. Does anyone know what could be causing all this?  Thanks
