Hi ethomas,

Opioid analgesics are not the firstline, preferred, or even most effective meds for neuropathic pain, which is one reason your doctor may be hesitant to prescribe them. As zorro13 mentions, sometimes a combination of meds is more effective than any of them singly. This is one reason why a neurologist specializing in PN is better than a general neuro.

Talking about pain to any doctor is a matter of candor. In brief, talk about the pain - being as descriptive as you can - and its effects on your day-to-day life. Google: talk to doctor about pain

For weight loss, I recommend the diet found at the back of The Intractable Pain Patient’s Handbook for Survival
http://pain-topics.org/pdf/IntractablePainSurvival.pdf
with your doctor's approval. I do not know if it is appropriate for diabetics. Once you begin losing, you should be able to increase your activity/exercise to help lose more.
