Brief Answer:
Probable peripheral neuropathy.

Detailed Answer:
Thanks for choosing HealthCareMagic for your health concerns.

I read your question and from the description it looks like a typical case of peripheral neuropathy.

Naturally the diagnosis must be confirmed by a neurological exam and exams like nerve conduction studies.

If those further steps reach to that suggested diagnosis the next thing to do is to look for the cause.

The causes can be many like diabetes (most common), chronic alcohol abuse, nutritional deficiencies, hereditary (less likely at his age), toxins, hormonal, nerve entrapment, metabolic alterations etc. At times cause can't be found.

Since the causes are many, many tests could be required, it's started by routine ones for common conditions and if those are negative it's proceeded to search for rarer causes. Some common tests include blood glucose and HbA1C, complete blood count, liver and kidney function tests, electrolytes, tests for thyroid function, Vitamin B12 etc.

Once the cause is found naturally it must be addressed to limit progression. If neuropathic pain remains an issue, treatment with anticonvulsants (Pregabalin, Gabapentin) or antidepressants (Amitriptyline, Nortriptyline, Duloxetine, Venlafaxine) are the usual first line treatment.
But of course that must be started once diagnosis is confirmed and since they are prescription medicines their use should be discussed with your doctor.

I remain at your disposal for further questions.
