Hello Doctors, Need your advise. My brother in law is having severe pain below the feet after going through a surgery in leg for blocked (clots) blood vessels. It hasn't even been a month since the surgery happned. Pain started after few days of surgery. He is still under medication but it is not working for the pain. He is not able to sleep, eat or rest because of the pain. I am also attaching NCV test report for reference. Kindly please help us to know the reason for the pain. Also please guide what should be doing about it? Could it be dangerous serious?
