Ken is almost through his third week of radiation and things are going as well as can be expected. Still chugging down the Boosts and only lost 1 pound last week. Some thrush and mouth sores have been causing him a great deal of pain, so his chemo doctor put him on a 25 mg. Fentanyl patch, with 1 tsp. Oxycodone as needed (usually 3-4 times a day.) He was doing well with this course; however, when we met with his radiation oncologist yesterday, he expressed concern with the amount of pain medication he was taking. He told Ken the pain would "increase greatly over the next few weeks" and if he were already taking strong meds, nothing would be able to help him with the pain further down the road. Any opinions or advice on this?
