Hi. I have had breast pain in my left breast for 11 months now. It is not premenstrual. It doesn't go away. I can barely wash in the shower. I have had a mammogram and ultrasound and they both came back negative for anything. My doctor can't give me any answers either. Does anyone have any advice? He put me on Vit. E saying it would take away the tenderness. It is not working and it is pain, not tenderness. Thank you
