Toprol-XL and i can hear

I have been on Toprol XL for approximately 2 years. I started out on 25 mg. for palpations and rapid heart. Then the dosage was increased to 50 mg. and now the doctor wants me to take 100 mg. I have freezing hands and feet. My eyes are either so dry or watery so that I cannot hardly see. I have at times terrible shoulder, arm and leg pain. My brain feels likes it's full of goo. I can't think.

I am currently wearing a King of Hearts monitor. I have sent approximately 15 transmissions. During the transmissions I can hear my heart speeding up. The technician who takes my transmissions keeps telling me that my heart is beating normally. If that is the case, then I must ask my cardiologist at my next appointment, why am I taking Toprol and spending $35 a month for the medication if my heart is normal? By the way I am NOT increasing my dosage to 100 mg. I will stick with the 50 mg. for now and am considering tapering off even more.

I'm on several medications for high blood pressure and heart palpatations due to mitral valve prolapse. I am on Cardizem 240mg, Enapril 20 mg, and now Toprol (1/2) of a 25 mg. a day. (in the morn.) Now I've begun to have temporary hearing loss. My ears will ring and then it's as if I'm in a tunnel for the rest of the day. At night my ears clear up and I can hear normally again. Is anyone else out there having hearing problems?
