My husband (who has bi-polar disorder) attempted suicide 7 months ago through poisoning with sodium azide. He has been left with peripheral neuropathy which is severe from lower calf down and mild in his hands. He is taking 1200mg(x3) gabapentin and 25mg amatriptyline daily along with two B vitamins. He is persevering with regular exercise to try to stimulate the nerves. Recent conduction test showed no improvement since last test three months ago. Has anyone else had eperience of PN through any kind of poisoning? Can anyone recommend any other treatment/supplements/ excerise that has helped? Does anyone have a success story of recovery?
