I have been seeing a pain specialist for many years. I am 63 years old, and have chronic pain in my low back, and left hip. My hip is constantly inflamed. I have had every kind of xrays, mri, etc. known to man. I also suffer from migraines. My dr has had me on oxycontin 15 mg time release tabs for over a year. Recently I changed insurance. They want me to try morphine sulfate or a fentayl patch(spelled wrong). I have paid out of pocket for another month of the oxycontin as I am traveling back and forth to Florida from TN, as my 88 year old Mother has been very ill. Please advise what medication is best with my symtoms.
