My blood pressure diastolic number is around 100 and I was diagnosed with Vitamin D deficiency at the same time. I'm now taking Vit D3 supplements and Lisinopril 20mg to bring down my bp (not yet working).  I had pain that never went away after a hysterectomy a year ago, gradually the pain spread to my legs, butt, and hip muscles.  It would get worse with light walking or after being on my feet or sitting.  It seemed like circulation to my legs was getting cut off.  Vitamin D3 turned off the pain and improved my circulation, although I don't believe it's repairing anything permanently.  Six years ago I used cholesterol drugs to lower my cholesterol.  It caused subtle muscle fatigue, but it took me 2 years to figure out it was the cholesterol meds.  Since then my muscles never seemed the same. I joined a gym to strengthen my muscles but never felt the "good" feeling from exercise and never was able to increase the weights I was lifting. Is this muscle thing a cause for the high blood pressure? Is this how Vit D deficiencies cause heart disease?  My cardiologist doesn't know how Vit D causes heart disease.
