Li Xu lifted the blanket and examined the patient's lower limbs.
Below the knees, both legs were as cold as stone, the left one especially so.
On the inner side of his left big toe, a coin-sized ulcer had formed, so deep the bone was visible. The surrounding tissue had turned black.
And all ten of his toes had taken on a terrifying bluish-purple color—a sign of ischemic necrosis.
This was—gangrene.
In Western medicine, it's known as late-stage thromboangiitis obliterans, or limb gangrene.
True heart pain plus gangrene. The blood vessels in his heart and limbs were all blocked.
It was like a tree with rotten roots and a withered trunk, ready to topple over at any moment.
'The situation is grim.'
