"i have only been with pain management for 6 months but suffered from debilitating pain (osteoarthritis, neuropathy) for years. i am hoping through the fentanyl patch i may have some consistency with my management of pain. have tried opana 15 mg x 2 and before that a morphine tablet (cannot remember strength). i also had percocet 10/325 every 4-6 hrs for breakthrough pain. the only thing that helped was the percocet but felt i was taking way to many; 150 a month. i got the patch today. i took 2 percocet initially because i had been without anything for 3 days and was really hurting 10+. my pain level is at 1 maybe 2 after 16 hrs of applying the patch. praise god! my only issue is a headache and not being able to sleep. i am not sure if headache is from sinus or patch?"
