It will most likely be some years before a definitive answer to this particular symptom is available.
I believe that the next few years will be full of discoveries regarding the exact pathophysiology of this disease that has caused so much havoc, unfortunately.
In the last few months, I have really read little about it, I think that at some point I became saturated with information about this disease, it is important to know about it but with so much bombardment from so many parts, mentally one could end up affected. But there is no doubt that it is necessary to know more in depth in order to be up to date.
GREETINGS @winy, good start of the week.
