Or, see her PCP and get a CBC, ESR, FBS, HbgA1C, B12 level, ANA and possibly an MRI of her LS spine so a professional, rather than amateur posters on TOTV, can make an appropriate referral.

You may want to do research on the following supplements for Neuropathy:
Alpha Lipoic Acid
Benfotiamine
B-12 and B-2
Acetyl L-Carnitine
Do your own research about the above supplements. They have been effective for many with Neuropathy. In addition, have a lab test for Vitamin D to be sure you are above the 30 threshold level.

Peripheral Neuropathy
 

Be your own advocate and research internet for a Neurologist and get referral from your PCP. I did things a bit backward and discussed my symptoms to a foot dr who only said i had weak ankles. Having had back issues for years, I presumed it to be that, and my chiropractor had a division of pain management who conducted epidural(s). I thought that would help with pain in my feet and legs, but once my toes became stiff and I no longer could stand on my toes nor back on my heals, my PCP sent me to PT who after a time said I should see a neurosurgeon. ?? This has been over a year's time, and I finally got an EMG (nerve conduction test) and extensive blood work showing results consistent with CIDP (chronic inflammatory demyelinating polyneuropathy). This condition is not back related by an autoimmune issue. Feeling very let down by the medical field, I am now in search of a neurologist specializing in it.

Foot roller - massager will definitely help
 

I have had burning feet for years and it’s not diabetes. I got plantar fasciitis in my feet when I got older. What helped me the most was a foot roller/massager I bought from Amazon. It breaks up all the stubborn tissue in your feet. The roller got ride of my plantar fasciitis and my sore feet. It’s an exercise tool I use often. Hope this helps

I agree with all the other posters about seeking medical advice. Something non-medical she may try to relieve some of the symptoms is to purchase a pair of compression socks and wear them at night. They can help improve circulation in the feet/legs and provide some relief to the pain, numbness, and tingling.
