I have been taking Norvasc for about 40 days. I have absolutely no strength anymore, I am dizzy, and I can see my heart beating when I look at something with solid color, it is like my eyes are flashing as my heart beats. My legs are hard to move when I first get up, and it is hard to get up off my knees unless there is something near by to hold on to. I was having trouble going down stairs until thursday of last week when I could go down them fairly fast. This made me feel like I was getting better, then the very next day I was taking a shower at home after working a full day and I almost collapsed. I barely made it out of the shower to sit on the toilet. My legs were like the legs of a parapalegic for about 1 minute.
