Does any of your medication cause side effects impacting nerves/nervous system?

I had “normal “ bloodwork at first but needed expanded iron and thyroid panels to detect iron deficiency and Hashimoto’s thyroiditis (autoantibodies).

My original recommendation stands to get the small fiber neuropathy skin punch biopsy by a neurologist. There is no cure but there are potential treatments.

Did you already go to a podiatrist for a look at your foot structure? You may benefit from orthotics/shoes for people with nerve pain. You may also want to have plantar fasciitis/tendonitis/nerve entrapment ruled out.
