First thing to do is find out what the root cause of it is. Nerve impingements, diabetes, injury, whatever. Once that is known, then you might be able to come up with a plan for treatment. Gabapentin/Neurontin, Lyrica, Cymbalta, Zonegran, etc all might work some, depending on what you tolerate the best. Mine is mostly due to impingements in the spine, mostly Stenosis, and numerous injuries of old. All of the aforementioned drugs had minimal, if any, positive effects. Lyrica caused severe edema in the lower limbs. Gabapentin was evil. Cymbalta didn't do a thing, and Zonegran was the only bright light, since it reduced my appetite. Can't eat when you feel sick from the drug. Didn't help with the pain. Stopped taking Gabapentin when the bloodwork came back. Scary drugs and sometimes bad side effects. There are neural electrostimulator implants like the ones that MedTronics makes. Some of their implant devices have been recalled, but those were mostly cardiac units. There are also med pumps that can deliver meds right where they are needed all day and night.
The main thing is to figure out what your options are and which solutions work for you. I had a bunch of surgeries and I'm hesitant to do more. I had them fix what was critical to prevent further paralysis and risk, and manage it with conventional meds. I tolerate those better than the anti-seizure stuff like Gabapentin. Was taking 1800 mg of Gabapentin per day, split in 3 doses. Needed to taper the dose upwards to get there and taper the dose down until I could stop it. It was prescribed "off-label" back then. Mostly used for epileptics.
Steroids like Prednisone can sometimes help if there is inflammation or impingements. Usually a week or so on a decreasing dosage can work wonders. If you are a diabetic, then be careful with the corticosteroids. They can play havoc with blood sugar levels.
