high blood pressure
"50 year old female.  Had been advised of borderline high-blood pressure for a few years. During an unrelated surgery & hospital stay, BP was uncontrollable and spiking 200/120.  Dr. started me on Metoprolol and lisonopril, but didn't control my BP well, and horrible side effects of fatigue, light-headed, loss of concentration, etc.  Switched to Bystolic, and immediately blood pressure was perfect, side effects were gone.  BUT WITHIN A COUPLE OF MONTHS - started having severe joint or tendon pain in shoulders, hips and fingers.  I've seen a few reports of this problem with Bystolic, going to an osteo specialist this week - I would hate to have to stop Bystolic, but if it's the culprit, these joint pains are not worth it."
