Yes, I agree. I would get B12 and Vit D tests as well. Get your number result so we can discuss them here. (doctors in US are still using old, outdated lab ranges and telling people they are "normal" when in fact they are not).

Poor absorption of nutrients can lead to paresthesias. Calcium is one big cause of odd sensations. Low Vit D would lead to poor calcium absorption, etc. Also use of acid reducing drugs, negatively impacts calcium absorption, as well as magnesium, B12, folic acid, zinc and iron.

When my thyroid issues caused my initial PN, it was hands and feet.

Gluten intolerance can occur without Celiac being present in testing results. And it can cause neuropathy.

This wonderful website resource has a separate section devoted to neuropathy, and testing:

Many nutrients can be malabsorbed if you have gluten problems and/or Celiac. Going gluten free will heal the inflammation and allow you to over time restore normal absorption. Taking some nutrients in the the meantime is important.
