Hello and welcome to the NeuroTalk Support Groups.

I'll post clickable links below to a few of the forums that might be of help to you.

Peripheral Neuropathy Forum

PN Tips, Resources, Supplements & Other Treatments Sub-Forum

Reference Threads for Specific Vitamins, Nutrients, Herbs, and Supplements

Traumatic Brain Injury & Post Concussion Syndrome Forum

btw, a change in the ability to smell (as well as changes in other senses), isn't that uncommon after a concussion. Same with anxiety. If you post on the TBI/PCS forum about those issues I'm sure you'll find a lot of information and support.

You could also use the Forum Search Feature for specific keywords associated with your symptoms.

take care.
