Spraying Yunnan Baiyao instead of more pain, mostly due to the stimulation of the nerves at the site of injury, the wound is open, and the drug has not yet taken effect and other reasons. Yunnan Baiyao is mainly used for bruises or sprains, which can reduce swelling and pain (eliminate swelling and pain), activate blood circulation and remove blood stasis (promote blood circulation and eliminate blood stasis in the body). Spraying Yunnan Baiyao instead of more pain may be due to the stimulation of peripheral nerves at the injury site, which leads to more pain. If the wound is open, spraying Yunnan Baiyao will also cause pain due to irritation, which requires cleaning the wound; in addition, the drug takes time to take effect, and in the process of taking effect, pain and other discomforts will also occur. Although Yunnan Baiyao is a commonly used drug for bruises, it is also prohibited for those who are allergic to the drug, allergic to alcohol and pregnant women, and may also cause hives and other allergic symptoms. It is recommended to consult a professional physician in a regular hospital.
