Toprol-XL and neck surgery

I developed a chronic cough while on Toprol. It got so bad I could hardly talk on the phone or sleep. Thinking I was developing and allergy, I went to an ENT doctor and an allergist. They treated me for allergies. By chance, on my annual physical with my regular doctor, I brought up the bad coughing. She immediately told me that it was my blood pressure medicine and changed the prescription. However, by that time, I had been coughing so hard that I ruptured a disk in my neck and had to have neck surgery. So, if you start developing a cough you can't seem to get rid of on this medication, please see your doctor immediately and don't think it could be allergies. I waited too late because who would have thought that blood pressure medicine would create a dry, chronic cough.
