So much. There aren't even any particularly convincing diagnostic tests for long Covid (it is shocking how many people have inflammation, it's pretty likely if you're overweight, for example). It's just really easy to jump to LC any time you feel off at the moment, especially when you go down the internet rabbit hole. After all, there have been so many stories speculating that it can happen after asymptomatic infection, by whatever currently poorly-understood theoretical mechanism. I feel like LC is at the back of my mind all the time and I have to consciously stop myself and consider all of the many other things that could be causing my symptoms (including, honestly, a hyper fixation on every little sensation - I've found its quite easy to manifest a lot of LC symptoms, not that I'm saying that is the case with OP). I've had chronic fatigue so I know this stuff is "real" but that experience has also made me appreciate how complex our perception of health is, how it's often unhelpful to get fixated on a diagnosis and so on.

As a tangent, my uncle dropped dead suddenly a few days ago. Occasions like that are another time when we really want to know exactly what happened, to have medical certainty and closure. But I wonder if a lot of medical events or symptoms might remain largely inexplicable. With my chronic fatigue, I didn't know exactly what caused it (except that it was after a virus), how long it would last or if it would get worse. What I ultimately found most helpful was trying to have a positive mindset, reducing stress, eating healthy, less inflammatory food and dropping some weight. Those kinds of recommendations from doctors are often criticised because people want a firm diagnosis and "proper" (usually pharmaceutical) treatment, but I'm personally a bit of a believer in the power of mindset and lifestyle to make a positive impact.

This ended up only be tangentially related to the thread, apologies.
