Im a 40yr old male that had an Ablation over 2 months ago. I am still taking Coreg, and Coumadin. I was on Amiodarone prior to the ablation. The ablation was a success acording to the DR.'s, but I have this feeling like someone constantly has their hand on my throat. I have to clear my throat probably every 20 minutes. This usually produces a white phlegm but there are no traces of blood in it. Additionally, I usually hit a wall in my jogging at 4 minutes and have to walk then run, walk then run to finish my exercise program. I use to be an average jogger doing about 3 miles 4-5 times per week. Now, I just keep hitting that 4minute wall and then I have to walk for a minute. Its really a pain. I have also put on a good 10pounds. I dont drink, or smoke. Has anyone else experienced these same symptoms. Thanks in Advance. Im thinking the phlegm could be toxicity from the Amiodarone, and the shortness of breath and weight gain the Coreg. Im doing about 40mg per day of Coreg.
