Hello, my father, age 60 is suffering from Diabetes from last 15 years, average sugar level around 250+ after lunch. From last two years he is facing lot of problem in walking getting up, numbness in his foot, dryness of fingers of legs, his legs pain a lot and also from last 3 months he has started with back pain. Pls. Suggest which doctor shall I suggest, as whenever I consult diabetologist he says we don't treat for legs, feet and back pain.
