Doctor: Hello, In a person with long standing diabetes, peripheral neuropathy does set in, particularly if glycemic control is poor. But even with good control also neuropathy does develop giving rise to burning pain in feet, tingling and even numbness. Itchy feeling is due to improper blood circulation and affection of venous return. Strict blood glucose control is a necessity. Drugs like Methylcobalamine and pragabalin can help in controlling pain in the feet. Strict deitary control, some amount of regular exercise along with glycemic control will help. Age is definitely a factor. Fasting blood glucose should be closer to 100 mg, PP 160 to 180 mg & HbA1c%<7.  Thanks
