How serious can neuropathy of the feet get?

You are asking questions which can only be answered by first obtaining a complete diagnosis. Speak with the doctor who made the diagnosis of neuropathy, and if not already under the care of a specialist, as your doctor about seeing a neruologist, or neurosurgeon.

 

My mother is diabetic and suffers with neuropathy. She has debilitating leg cramps that constantly wake her at night and she also suffers with nausea as an after effect as well. The meds that are prescribed to her do nothing for her so she has started taking OTC leg cramp meds she found at Walmart. They offer temporary relief but only after the onset of said cramps.
