Chest pain and Palipations daily for 6 months?

Atenolol can cause the symptoms you describe, however, I know you are not an idiot, so it may not be this. How long have you been on it? Is there a corrolation? If not I will tell you, that I have had the same symptoms, and xanax didn't help. Valium and effexor. Valium was the big one. Anxiety can make your body go nuts, and even though I didn't feel anxious, I still had anxiety attacks. I hope this helps.
