Those are my symptoms on day 9, 3 days after an antiviral infusion.
There were also symptoms when I had it in October 2020, many of them stayed with me to some extend since that infection, some 15. months ago. I was diagnosed with long covid.
Keep an eye in your blood pressure. In my first infection that was a major issue. It rocketed so high (was well over 210/120 and wouldn't come down)I was hospitalised. I will now be on two different blood pressure medication for life. It was raised slightly this infection, despite the medication, but has stabilised again.
My heart rate has always been fairly high. I used to have SVT which was repaired with ablation in September 2019. In both covid infections it's been high on exertion. This time round it increased when I move - to around 140-160 bpm. It's now dropped to about 130-140 bpm when I move, so slowly improving,
The chest pressure feels quite high up, towards the top of my chest. It varies throughout the day but doesn't really go away. Last time this improved gradually over the weeks/months but returned if I was very tired, off colour, etc.
Just give yourself time to recover and don't try to push yourself too quickly. Mine did improve gradually but didn't go entirely.
