My husband's PN came on in the hospital during his treatment for Aplastic Anemia. They too had no solutions for him except more drugs and he was not having any of that.

A couple of things to consider. Look at the medications he was on in the hospital. They can have neurological side effects. And, since he was on a ventilator, I would venture to guess that the nutrition provided was less than optimal. Probably also impacted his gut health and the microbiome needs to be restored.

So I would suggest addressing nutrition that support the nerves and mitochondria. Aside from the B12 (methyl form) and other B vitamins, Alpha lipoid Acid made a big difference in his pain level. Within two weeks, he noticed improvement. There's a new form of the vitamin called R-Lipoic Acid which is supposed to be more bio-available.

He also did chiropractic adjustments which corrected his gait. His gait was totally off from being in bed in the hospital for so long.

We also invested in a device called the Rebuilder which is like a tens units. This really helped him a lot. Not everyone has the same response though.

Also, cool foot baths in epsom salts can help. And keep the feet really moisturized with a good foot balm. Kind of acts like an insulator for the nerves.
