It depends on what kind of pain(s) you're experiencing, I would have thought.
I have a pins and needles sensation in my feet / hands and occasional, shooting pains or a short lived sharp throbbing pain from time to time, which has been diagnosed as Diabetic Peripheral Neuropathy, in other words nerve damage in my extremities, this was misdiagnosed at first - so it may be worth your while asking a doctor to rule this out. If it is DPN, it is treatable.
