My 25 year old daughter developed acute pericarditis 5 weeks after her last ablation for massive PVC's. She was given 1500 mg a day of Motrin to begin with and then after 5 days of no progress, switched to colchicine twice a day along with Naprosen and low dose Vicodin as needed. Her pain has become much worse. She has a very high pain threshold (her last ablation was 7 hours long and she had no anesthesia at all) and now cannot sleep and has dropped one class from her law school schedule. She indicates that the pain in consuming her entire life, especially in her left arm. Her EP seems reluctant to place her on the Predesone protocol. Are there any other avenues to pursue? Thanks for your help!
