question: 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
