I have been monitoring myself and testing myself on this strange discovery...
I got down in on knee (on a non flare/rash day) for about less than a minute and put not that much pressure on it...and got up and went about my business...
the weirdest thing was that within an 2 hours the lupus attacked that knee and a red lupus rash appeared in the exact pressure area i kneeled on !!!
I also tried on a tight sock and to my surprise on another day...it attack the exact sock pattern in the lupus rash ,,,
Thought i would share this interesting observation.
So as soon as my body notices externally humidity, heat, pressure it goes to war !
