I have been on Lisinopril for 6 days...taking 20mg along with norvasc 5mg. I don't have headaches usually and the last two days I have had sharp and very painful headaches, my throat started hurting yesterday and I had cramps in my abdomen, sides and legs so severe that I cried last night and I could not sleep. I am glad that I found this website. Besides all that, if I walk more than a few steps I feel as if I have to lie down and my heartbeat is very high. It is not the Norvasc 5mg....I have taken it for 3 years or so. Calling my doctor and changing meds....it did reduce the BP, but I can't put up with this pain.
