My experience with my hypothyroidism (which was mostly a compressive type PN):

I had pain in the feet to begin with. And numbness and tingling in the hands. Eventually the feet stopped hurting..and became numb. The hands would go numb on the steering wheel of the car or when I wore gloves, and at night sleeping.

The hands were the worst, and during my pregnancy were totally disabled and I had horrendous pain at night. Once I delivered most of the hand issues resolved to about 10% and would flare some with stressful activities. I continued to wear my braces at night for years after. I still do at times of flares.

My feet finally woke up when I was diagnosed with a goiter and low thyroid. I had tingling and pins and needles for many months and finally they went away after a year or so.
So I equate numbness with severe nerve compression at least for myself. Numbness that does not vary with the daytime activities, is worse than occasional numbness. I can get numbness in my hands when I have low blood sugars today. But it goes away when I eat something.
