Seems like some confliction on causes re: neuropathy and thyroid from Mayo. This link does mention underactive thyroid.

Perhaps digging deeper into thyroid COULD help reduce pain. I just know I spent a lotta years getting thyroid supported due to numbers and not symptoms. My D.O. back in 2002 called in for Armour, no labs, he knew as he was from the older school of doctors. I went untreated for 10 yrs due to NORMAL numbers.
