I've been on 100 mg of Losartan for about three months now and have had neck discomfort the entire time. It's a weird sensation, not really swelling, not really pain, just discomfort. It's not lymph nodes as I know what that feels like. I also get a kind of metallic taste in the real of my mouth behind my molars. Has anyone else experienced this? If so does it go away? I have an appointment with the doc in April.
