I've responded to you via PM today, more completely.

But please Liftyourhands, post more details on your lifestyle.
We all have to be detectives to find what it is that triggered you into PN symptoms.

Diet can be a big factor, and some people with gluten intolerance develop malabsorption of nutrients from the intestines. When this happens you can develop deficiencies in addition to neuro symptoms. Getting tested for B12 and Vit D is a good start.
But minerals often are affected as well. Magnesium, zinc for example.

If you use OTC medications alot, like Zantac or Prilosec, you can become low in 6 nutrients: B12, folate, magnesium, iron, calcium and zinc.

PN is mostly a lifestyle problem, meaning something in your life is not working well for you. Sugar control, poor diet, gluten intolerance, other food allergies, exposure to toxins, RX drugs, vaccines, dry cleaning clothes exposure, pesticides, and many more. So looking back at your LIFE when this started, and carefully looking at your home, office, food, hobbies, can sometimes provide hints, so you can correct that.
