Completely off the Fentanyl for over a month now. Only on 3600 mg gabapentin/day, .5 ml of 20mg oxycodone as needed & Lidocaine topical as needed. I rub a small amount of lidocaine on site of surgery quite frequently & don't use oxy a lot. I have found a little relief using ibuprofen at 400-600 a pop but don't want to end up with stomach problems. Now the doc want me to go on methadone & get off the oxy. They have not figured out why the pain is persisting. Some days are not bad while others are really bad. They say the radiation is still leaving my body. Is that still possible 8 months after radiation? Won't methadone be just as bad as oxy as needed?
