Hello Shona kramer,
I'm so sorry to hear that you've lost your loved ones in such a short time, that must have triggered your symptoms.
They are all related to what is called peripheral neuropathy, which can have many different causes like diabetes and other metabolic problems, connective-tissue disorders and other autoimmune disorders, infections, toxins and trauma.
I have been experiencing burning feet from the early stages of perimenopause and now in postmenopause I also have burning hands and arms. It happens in flares, sometimes along other symptoms like joint aches.
After many appointments with different doctors and a number of tests it looks like some sort of autoimmune disease yet to be diagnosed but they all have agreed that ANXIETY plays a major role as a trigger. Low oestrogen levels may also play a role but since you're 7 years postmenopause I reckon this is not your case. Are you taking HRT? Hopefully your neurologist will find some answers and please keep posting, I am really interested in knowing how it goes.
