question: How can the intake of 5 mg daily intake of Acitrom due to Aortic valve replacement in Jan. 2000 by a 63 years old can be co-related to the problem of sensory nerves weekness, including the problem of ED. Also pl. let me know if there is any more safe alternative to Acitrom or lesser dose of Acitrom, for maintaining INR at +2 level in the increasing age. I also start feeling numbness from knee till ankle and medium level pain in left foot after standing for 15 -20 minutes or walking for about 1.5 - 2.0 Km., which presently disappears after a rest of 5 minutes and i can walk another Km or so only. How can i lead a reasonably comfortable retired life with an hour+ of Yoga and Pranayam daily in the morning, followed by a walk of 1.5 to 2 Kms.? I am otherwise a tea totaller and pure vegetarian, not even eggs or fish and non consumer of alcohol or beer etc.
