Ouch! That's not easy for you. ? Merino wool has great thermal properties and doesn't get smelly as quickly as most materials. It's great for socks and underwear but I don't know if it would be hard wearing enough for gloves. Bamboo fibre is nice next to the skin too but I don't know if it's as warm..I have issues with nerve damage after breaking my back, once the temp dips below 8c my fingers can start to feel numb, it's exactly the same with my feet, our fingers in this job don't move all that much so my hands can go ice cold and be quite painful rapidly on a winters day I have even tried taking painkillers to manage the pain but nowt works
