A combination of low dose amitriptyline (10 - 50 mg at night) plus
gabapentin (300 - 1800 mg per day) or
pregabalin (50 - 600 mg per day) produces the best pain relief with the lowest incidence of side effects. (taken from some site I don't remember)
Tegretol, Neurontin, Lyrica, or Keppra are the most used medicines
Antidepressants and anticonvulsants are also used
Hope that helps, my father just had a severe stroke and we are still waiting for his recovery.
