I am on my 2nd reccurence of oral cancer. I am in a great deal of pain all of the time. I have a tumor on my jaw, open wound on my neck that leads into my mouth so I have not drank anything in 6 months, and I finished radiation in mid june. The doctors have me on oxycodone 30mg every 4 hours, methadone 15mg, and gabapentin. I still seem to be in pain most the time, its only about a 4 tho. My major problem is I am going to have to stop taking the methadone. This medicine is making me fall asleep even while I am standing. I went to the restroom went to wash my hands and I fell asleep standing there. I then fell, I was lucky because I fell right in between the toilet and the bathtub. So I just missed slamming my head into anything. I only hit my arms. Anyone else have this problem with these medications? And does anyone know some pain medications that may help me? I just want to be out of pain, even if its not all the way I want to be a lil more comfortable. I have also tried the fentanyl patch, that makes me sick and I can not take oxycotin because you can not crush it and put it down a gtube. Any suggestions please.
