Never heard of knee knead syndrome?
The main symptom is an odd pattern of red markings all over your kneecap...and you have no recollection of how it got there!
It's what happens when your cat kneads your knee cap, you're wearing shorts and you have a spinal cord injury and can't feel it.
You may have Knee Knead Syndrome if....
Folks ask "What happened to your knee?" and you say "Dunno."
Later in the day you notice your cat kneading away at your kneecap.
You haven't fallen on your knee(s) lately.
You've excluded all other reasons for red markings on your kneecaps - allergies, installing carpeting, etc.
May post a photo sometime of this new medical condition....
