I have a diagnosis of atherosclerosis and vitamin D low levels (16). I have a strong family hx of heart disease, my father died at 53, mother with CVA x 4 and my oldest brother had blocked arteries in both legs requiring surgery. Lately I have had extreme pain and acheness when walking (grocery shopping) and going up and down stairs. I have a hard time opening packages, seems like I have no strength in my arms. I have plaques in both carotid arteries, HTN, high cholesterol, asthma. I take multiple medications and have done so since 2008. At night when I try to sleep my legs will throb. Is this related to PAD or could it be from low vitamin D levels. I usually am extremely tired after shopping and fall asleep when I rest my legs. Any input will be appreciated.
