I have breast cancer. I had radiation treatment over two months ago. I am experiencing extreme pain (10) on my breast and back. I cannot use my left arm where they removed my lymph nodes. The pain is almost unbearable. I cannot wear a bra, any tight clothes, and everything hurts. Is this normal. The doctor has me on pain medicine, steriods, cancer medicine. It is progressively getting worse. What can help? Elaine
