You should absolutely ask for a referral to a neurologist, who will do EMG tests to determine if you have peripheral neuropathy or not. I have SFN (non-diabetic) and have been taking ALA for a year or so. Honestly, I don't think it's had any affect. I've read all the literature, and the neurologist I saw said it won't have any negative effect. But it's far and away not something you can expect to control your neuropathy, especially without doing more research into what might be the cause.
