I am 78, male, retired after 42 years of active work in shopfloor of an automobile industry and spent my last ten years in marketing. Had a very active life. Oflate (for last 6/7 weeks) I am having pain in my left leg calf muscle. This pain has now spread upto my hip .I am not able to walk even a minimum of 100 meters at one stretch, without sitting .This has spoiled my morning walk of 2 to 3 Km. I am not diabetic, BP is normal Can you suggest means to get over this pain in left leg. I am a pure Vegetarian.
