I sit on my feet
Discussion
OK.
Sit on feet, compress sciatic nerve at buttock, makes whole lower leg go numb. Stand up, nerve breathes again. Reversible.
Or,
Sit on feet, blocks arterial supply to feet, feet go numb. Stand up and blood flows again. Reversible.
You are either compressing a nerve or an artery and up to about 2 hours of this is totally reversible.
If you overdose on heroin, and lie on an area for 12 hours without moving (as they do) Then you get irreversible changes and sometimes we amputate a limb for this.
