I take benzapril 10-20 mg. My blood pressure rises at night when I lay down. I’ve been doing this for almost a year. About 2 1/2 months ago I started having pain in knees, legs and ankles. Some swelling in right foot. However cutting down on salt consumption has stopped the swelling. I still have leg pain and the worst is at night when I go to bed. The most pain is in the back of the leg behind the knees. I’ve had blood work for kidneys and diabetes and liver. Also an ultra sound for liver. All good.
