I'm a 20 year old underweight male and usually 165/100. Since it's been like this for a few years I decided to go to the doctor's, and was first given metoprolol. After 2 weeks I couldn't handle its HORRIBLE side effects and was switched to 10mg lisinopril. Its been a month now and the only side effects I'm experiencing are shortness of breath and muscle aches throughout my entire body. It feels like everybody else said--like you worked out way too much the day before, except EVERY day. I've never had muscle strains in my life and have already had two in my legs and one in my arm, but even lifting a heavy box that would normally be no problem feels like it will rip off my arms and break my lower back. I don't know how you people keep trying different drugs and failing, if the next drug isn't perfect for me without any side effects I'm giving up and will just live happily ever after with high BP like I was before. Thanks for helping me figure out where these muscle aches are likely coming from!
