The correct way to use Yunnan Baiyao aerosol is to spray it on the injured area, usually 3-5 times a day. If the pain is still not relieved, spray the aerosol again after 1-2 minutes, preferably no more than 3 times a day. If the pain is not relieved, it is best not to use it more than 3 times a day. After a 3-5 minute interval between spraying with the Yunnan aerosol safe solution, then spray with Yunnan Baiyao aerosol. However, in addition to spraying Yunnan Baiyao, the foot should be diagnosed and treated by an orthopedic surgeon in a timely manner to avoid any misdiagnosis of ligament or bone damage.
