The acute phase of bone fracture is not suitable for hot water foot scalding, because in the acute phase of bone fracture blood vessels rupture and bleeding, scalding the foot with hot water will lead to vasodilatation, which will lead to increased blood leakage from the local ruptured vessels, resulting in the formation of severe local swelling, which is not conducive to the healing of the fracture location. It can also lead to increased pain, swelling, and unfavorable movement, and may lead to increased pressure on the bony fascia, which can cause necrosis of the distal end of the foot due to compression of nerves and blood vessels. If the bone fracture has passed the acute stage, especially after 48 hours when the blood vessels have basically closed, hot water scalding can be performed, and the process of scalding must keep the foot relaxed and not active, otherwise it may also lead to the re-emergence of small local blood vessels and swelling. In the acute stage of bone fracture can be applied cold water soaking or cold compress, can make the small ruptured blood vessel wall closed to reduce bleeding, can help to avoid the formation of swelling in the location of bone fracture.
