My father is 53 years old. He is having a problem in both the legs. Whenever he walks he starts feeling pain in his heels and the nerves. He gets a sensation of current from his heels to the waist through the thighs in both legs and it pains severely. The pain is so much that sometimes he is not able to walk. He has pain in his veins. He also had his hernia operation done in april 2013. Please doctors help me with suggestions.
