Shortness of breath, foggy headed, joint pain, weight gain, stiff neck, clicking sounds, loss or flexibility of joints, tired. Felt old! Went on Toprol-xl for maintenance only. Never had high b/p. Talked with a friend, then found this web sight. Guess I'm not alone. Guess it's not me! Changed doctor now, one that will listen. She urged me to go off it and monitor my b/p. Took about 2 weeks, been off for a total of 3 weeks now. Feel great. Most symptoms are gone. No more inhaler and feel better. Clear headed again. Blood pressure is now high though. Don't know if it's me or the drug. Don't know if drug has done any damage. Had an ekg done. Dr. said heart is working to hard now. Wants to do a complete stress test. My wife and I are worried if its the Toprol-xl wearing off, or not. Anyone else had an ekg done. Does Toprol-xl damage your heart? Need answers. Looking for feed back. I'm only 53. Never had health problems before. Thought I was just growing old!
