男人从椅子起身时感到腰腿疼图片

A Chinese office worker experiences sciatica, with red infrared thermal imaging highlighting the pain area on the buttocks and the back of the thigh. The image is extremely clean, with a completely white background, no background clutter, no decorative lines, and a complete view of the lower body and buttocks without cropping. The aspect ratio is 3:4. Commercial photography, medical education style, high-key photography.
