Side Affects post Ablation

I had an ablation for AFlutter 3.5 weeks ago. I’ve not felt good since. Fatigue, nausea, malaise, some sob and it’s uncomfortable to take a deep breath. Is it common to not feel well after ablation? They started me on Flecainide but that made me feel worse. Stopped it last Saturday with my cardiologists approval. Just wondering what most folks feel like after ablation. I’ve been in NSR, HR in the 50s, BP Avg 115/70, pulse Ox 95-98%
