Hey Richard - thanks for your message. More fellow long haulers have contacted me reiterating the same. Back last year, I couldn't find a single soul who had the 'storms' in the lungs like me. They still don't know what it is unfortunately. I haven't been able to test the storms after activity as I've been largely bed bound due to new 'heart attack-like symptoms'.
The good news is the blood thinners have pretty much dissolved the clots in my lungs now.
If I find out what is causing the storms, I'll be sure to write a post about it.
Wishing you all the best in your recovery.
Jasmine
