I am 75 years old, ht 171 cm and wt 67-68kg. I had heart surgery in 1994. After that I am well, but use everyday heart-medicines including Kolestero medicine Lipitor (80 mg/day). Once in a year I visit Kardiologist; doing well. Last one year,I have Cytica nerve pain. What type of doctor I should visit for it? I can not walk for more than 500m. Terrible pain in left leg and lower backbone. Pls do advice what I should do ? Physiotheraphy is good ?? With best, Arun
