If you're lucky. I have similar symptoms, and I'm 18 months in and still not back to normal (I have improved, but intense exercise seems to cause a regression).

> It looks like most of the damage is first done to your blood circulation system and then that harms some other organs.

It seems to vary between people and infections, but that's certainly one of the ways it can go.

EDIT: Not sure why this is being downvoted?

There's a strong vibe of long covid denial on HN and some people are quick to point to a study that stated long covid is mostly a psychological issue.

Not denying that it could be long COVID but those are also the exact symptoms of chronic anxiety, which your COVID infection could have created or aggravated. You should check a doctor because chronic anxiety can be a real long term issue and it's possible to heal completely if treated seriously and rapidly.

A lot of people are developing anxiety symptoms due to the epidemic crisis. I think it's worth checking.

At Dr’s recommendation, see a psychiatrist, dr gives me some anti-anxiety medication to try, and I feel better almost immediately. Spend a few months working on behavioral response to stress, breathing exercises, etc., then go off the medicine. Total game changer.

The mind and human body are funny things.

While I’d guess some “long Covid” is related to serious cases that caused underlying organ damage, my suspicion is in the more general cases where vague symptoms are described it’s probably anxiety.

In my case, I'd been dealing with anxiety my whole life, but it never caused physical symptoms. Then I had covid, felt better for 2 weeks, then suddenly started experiencing low-grade fever, night sweats, fatigue, no appetite inability to sleep for days on end (this was the worst. would feel like I stopped breathing whenever I started drifting off, and it felt like my body would then jump-start itself and violently kick me back awake). None of my doctors knew anything about long covid, and I started to wonder if I was dying of cancer or something. The symptoms were distressing enough to make anxiety a logical response. So, yeah, at some point, anxiety probably created additional symptoms, or made me more distressed by my symptoms, but neither I nor any doctors I've met believe anxiety can cause a fever, at the very least.

For me, I've experienced the difficulty sleeping, early morning wakefulness, heart rate, nausea, stomach issues, and sweats as physical symptoms of anxiety. A big/scary event (getting covid, death of family) can make the physical symptoms more apparent.

Not sure about low grade fever, but it wouldn't surprise me.

Again, doesn't mean it's not something else but I think people tend to dismiss anxiety as someone not taking the claims seriously - when to me anxiety symptoms are serious and miserable, they just require different treatment (unfortunately Hypervigilance makes things worse when anxious about symptoms and thinking they're not anxiety related).

I still have a hard time telling the difference between actual infection/physical illness and anxiety personally even knowing all this about myself - it's hard.

That sounds a lot like sleep apnea, and will kill prematurely if left untreated. You should get a sleep study to check that.

Medication really helps to get over it and stop the circle when symptoms are moderate.

It would seem to me, based on the above, that you are experiencing anxiety about the long COVID issue and thereby exasperating the “symptoms”.

Iirc two of the most effective prevention of death in clinical settings around here before vaccines and this new type of meds has been the introduction of antibiotics soon after admittance (for older patients) since it prevented bacterial pneumonias to occur opportunistically (many older early Covid victims died of this even if Covid was the initial infection). The second one was to put anti-clotting agents early on after admittance to prevent secondary issues due to clots.

I'm 40, I got Covid-19 in Christmas, I got the second shot of Pfizer last July. I did not have a fever, I was just very tired for a few days. Then cough came. One month later I still feel something in my chest, I cough a little when I talk, and I collapse on Friday morning, instead of Friday evening, after a week of work (so I have a little less energy than before).

I'm doing push-ups, pull-ups and one leg squats as before. No problem there.

> Now that more than a month has passed since initial symptoms, I still feel that my heart and blood circulation is not back to normal and I am a bit afraid to exercise. I only do some walks on a moderately steep trail and some stretching.

If you have vaccine you increase the risk of cardiovascular issues.

Then if you get Covid you have risk of cv issues from Covid as well.
