I have been taking 25 mg. of Toprol for about a year. I am 48 years old. For the past several months, I have been fatigue, having chest pains, swelling in my feet and severe muscle weakness and joint pain. My head throbs on just one side very often and I feel light-headed. I have had complete blood work( including a sed rate) an EKG and stress test, all coming back NORMAL. From everything I have read lately, I believe that my problems may be from the Toprol.
