I have breast pain in my left breast, radiating into my shoulder, arm, hand and at times even into my leg. All left hand side. My hand actually becomes numb at times - sort of pins and needles. I cannot find any lumps in my breasts - I had a mammogram six months ago and have a few cysts which I was advised to just leave as they were. I am perimenopausal also so I am not sure if that may have anything to do with it. Generally I feel well.
