What do we know of the post-infection effects of Covid-19?

I had (suspected) covid-19 at the beginning of March however at the time the UK were only testing people who had been to China/Italy or had been exposed to a *confirmed* case. 
I wasn’t severe, however had a horrible cough for the duration and a very tight chest towards the end. I was just about ready to return to work when my institution was shut down. 

I’ve found that my lungs are still very tight when exercising (like that of an asthmatic) despite no history of this. Is there any evidence for lasting effects?

We know little of the long-term outcomes following COVID-19 recovery, simply because there hasn't been enough time to carry out these studies yet. So anything you hear or read is going to be based in some part on speculation.

That being said, many patients infected with SARS classic went on to develop permanent pulmonary fibrosis and reduction in lung function. However, these both improved somewhat over time. 

So if SARS classic is any guide, you may see some permanent loss of function if you had severe or critical disease. But if you are currently experiencing a reduction in lung function, that reduction is likely to decrease over time.
