男人攥着手腕感到手腕疼痛难忍图片

A young Chinese person watches their thumb, showing signs of tendonitis ("Mom\'s hand"), with red infrared imaging highlighting the pain area at the base of the thumb. The image is extremely clean, with a completely white background, no background clutter, and no decorative lines. The composition is complete, with the upper body and both hands fully visible without cropping, in a 3:4 aspect ratio. Commercial photography, medical education style, high-key photography.
