Alkymst,
The cold and burning pain you are experiencing simultaneously are nothing new to me. I've suffered from this for several years now. And I've found nothing I can tolerate (dryness) that touches this pain. It seems to go along with the territory, Small Fiber Sensory Neuropathy (SFSN).

Glad to hear of your weight loss but your B12 is deplorably low to have been supplementing with that much daily.

Melody,
Most opiod meds don't do much for nerve pains. It takes a combination for most people to get relief. The last few weeks as I've suffered from the sacral breaks, I've found that the Loritab they gave me for the bone pain, combined with the Lyrica for the neuropathy, really makes no difference in the level of the burning pain from the SFSN. It seems to stay.
