Diagnosed in Aug.2010 with sclc. Dr.s treated it aggessively with 4 rds. of Chemo and 37 radiation treatments of the left lung and sternum at the same time. Then 12 rds. of pci. In April 2011 Pet Scan showed no cancer. Thank God. But my problem begin in Feb. and contiues to cause me great pain today. Pain seems to radiate from my lower left rib around to the sternum and my back and up under my left arm pit. Continues pain, sometimes sharp stabbing pain. Also my left breast has a stinging, numbness sensation. Dr.s said it was scar tissue and to take every four hours pain med.s and ibuprofen. Which doesn't help. Does anyone else have this problem. Does anyone have any suggestions. I hurt so bad I can't do anything.
