My husband has prostrate cancer and bone cancer. He is on long acting morphine and short acting morphine. they put him on 10mg of methandone. He had a scab on his knee and it was bleeding. On his right forearm there was a little pinhole. It started bleeding. We went through 2 bandadies which were soaked in blood in minutes. I put the septic pencil on it and it stopped. Is the bleeding caused by the methadone. He is taking 10 mgs a day.
