MOnica I'm by no means an expert on pain (apart from being a sufferer of all sorts of pain). A few years ago, I was referred to a pain consultant, who explained quite a bit, including the differences between neuropathy, neuralgia and another kind of pain, the name of which I've forgotten.
I know for a fact that I have diabetic neuropathy, which is the result of nerve damage. The damage can't be repaired or reversed; the best I can do is try to prevent it from getting worse and taking appropriate painkillers, which belong to a specific group.
I also have neuralgia in my hip, which is not related to neuropathy, but flares up occasionally. The painkillers I take for neuropathy don't touch it, so I have to take painkillers from another group, which do work for the pain but (together with the neuropathy painkillers) leave me feeling like a zombie for much of the time.
My GP told me that many patients take the wrong painkillers, which unfortunately don't improve the pain, but do leave people feeling like zombies.
I'm currently starting investigations for the hip pain and have been referred to a consultant, although I have no idea when I'll be seen. I've had tests for vascular issues, which were negative (thank goodness), have a DEXA scan booked for next year because I have been diagnosed with osteopenia and take an aromatase inhibitor after breast cancer treatment, which is known to affect bone density.
It's important to know what kind of pain a patient has, so that the appropriate medication can be prescribed. All medications have side-effects, so it's important that people are at least taking something which will be effective and not suffer the side effects in vain.
