What Causes Weakness And Loss Of Balance When Treating Peripheral Artery Disease?

84 year old male with history of PAD, claudication no longer a problem due to daily walking, exercise, right diet and medications such as cilostazol and ramapril. My main problem is progression of weakness, a perception of impending loss of balance and feeling ill daily. Cardialogists have done angiograms and angioplasty and would not do stenting...too risky. I can live with that. What I don t accept is the progressive weakness and feeling ill 24/7. Have been checked out by neurologists also....MRI etc. ruled negative. Most MD.s that I have dealt with want to treat the symptoms with medications, but no one have come up with a diagnosis or cure. Would love to be around for at least another five to ten years. Golf twice a week..nine holes. Any suggestions? YYYY@YYYY 707-738-4123
