Not much I can say mate.

I hope you get well soon and recover speedily. It sounds like you have a powerful case of CV and it is insane how varied the intensity of symptoms can be from person to person.

I'm clearly uneasy about the asthma element and need to get that under control. I'm trying not to exert myself at all, but the restricted airways and heaviness feeling in my chest is unavoidable as is. It creates an entirely unpredictable element to this for me which is life-threatening

Absolutely! And that would be my main reason for saying to try not being too strong and silent, if the breathing issues get any worse m8, call the ER if it gets any worse.

Much love, and healing m8
