Mrrzy, "Sympathy!!!!!"

And some distractions?
The colourations you've described do indeed sound as though hydrostatic pressure waves were cruising through whatever soft tissue was there to take them. The parallel stripes probably indicate locations of particular muscles, which would be more likely than tendon to conduct pressure waves (tsunamis?) down into the foot and past the knee into the thigh.

I gace up on trying the physics for the reason outlined by folk1e. And I agree, it DOES hurt.
But it will go away and the colour transitions will take some time to complete.

Cheers, Rowan
