Went to see doc today for a follow up appointment. They are now saying they want to discontinue Test because they did an EKG and said I have a right bundle blockage. After looking around online I dont see any instances that Test could cause this issue. I told them what my past drug use has been because of Cluster headaches. One drug that is commonly used is verapamil and imitrex injectables. I think these played a role in this condition I now have. I just started Test on the 16 of August. As well as arimidex. Has anyone ever heard of test and arimidex causes RBBB? I have done a bunch of reading and can only find things that relate to verapamil and imitrex as well as inherited , and other causes such as heart attack, hypertension, and high blood pressure. As far as I know I have ever had any of these.
