Tested positive at the weekend after my daughter brought covid back from school. Am double jabbed and I'm guessing I'm on about day 6 ish of symptoms. I'm getting some really strange heart sensations and dizziness. Overnight my heart rate was going down to about 45-47 (resting). Today it's more normal, but it feels so odd. It's like I'm really overly aware of it and almost like palpitations. I'm also feeling really quite dizzy. My oxygen levels are totally fine. No cough or breathlessness to speak of. Has anyone experienced this? I'm finding it quite stressful!
