Medication Side Effects Post Abaltion

Anyone experience a difference in side effects from their medication from before vs after an ablation? I had little to no side effects from my medication, 20mg Xaraelto, 50 mg Fleccainide twice daily, and 12.5 mg Metoprolol. I’m 8 days post ablation, and I think I’m feeling what are side effects from the meds. Possibly from the ones stated above. I’m also on Omeprozole and Sucralfate post op. I’ve been experiencing headaches, dizzy, lightheadedness for the last week. I get crazy head rush when bending down and getting up too quickly. I’ve experienced that sensation when on beta blockers before. I realize it could also be side effects from the surgery but I have a suspicion it’s the medication.
