What Causes Severe Numbness In The Feet?
Possible peripheral neuropathy.
Detailed Answer:
I read your question carefully and I understand your concern.
When it comes to numbness of the feet the first diagnosis which comes to mind would be peripheral neuropathy, damage to the peripheral nerves. It can be due to many causes such as diabetes, alcohol, nutritional deficiencies, metabolic and hormonal alterations, rheumatological conditions etc.
For that reason in order to search for a cause some tests are needed, starting with nerve conduction studies to check for nerve damage and blood tests for the above mentioned causes, starting with the most routine ones like blood count, glucose, HbA1C, liver and kidney function, electrolyte panel, thyroid function, vitamin B12 etc.
I remain at your disposal for other questions.
