Hi doc! My mother who is diabetic has tingling pains in her foot from last two months and last week doctor gave NERVIJEN P capsules and told to eat once a day. But it has been a week pain didn't got away so I would like to know whether this medicine is recommended for this problem, if yes then why there is no relief even though one week already passed. Also if you could provide any other suggestions to get rid of the pain I would be really thankful. Thank you.
