I have explained it to the doctors. They say that it should ease up, but it hasn't. Not one bit. I am only doing 80% and it's extremely painful. They ask halfway through if i can go up to 85% and I absolutely cannot. I can barely make it through 80% without screaming. I agree that something is very wrong here. These doctors are at Johns Hopkins and really seem like they know what they are doing. They have done this for years, numerous times. It's so bad that I cannot sleep. I'm having panic attacks just thinking about the pain. I can't even talk or berate during the 4 seconds of pulsing. My thumb does not twitch but my teeth chattered uncontrollably last time. They spent a great deal of time making sure the positioning was correct, and rechecking it throughout the treatment. This is just an awful experience. I can't even describe the intense pain. I will never be able to tolerate 120% so I may as well stop now because this in ineffective.
