I just moved from one state to another, and I have been fighting to get my prescription of Lyrica filled. The pre-auth has been denied twice so far. I have severe peripheral neuropathy due to fibromyalgia, and I also have irritable bowel syndrome, anxiety disorder, atrial fibrillation with tachycardia. Due to stopping Lyrica cold turkey, I am experiencing a-fib, anxiety, racing heart, dizziness, and nausea. I am very afraid as I do not want to throw a clot. Should I go to the ER?
