Hello, I have , over the last month, experienced and sharp pain accompanied with a horendous burnning in my right breast. It is upper right area and the pain is sooo bad it wakes me up at night in tears. What could this be ? I am no longer child bearing, 40 years old, and no implants.. I have never experienced anything like this before. I had a hysterectomy when I was thirty due to a cancerous tumor on my uterus also.
