It's useless without open trauma. Iodophor has broad-spectrum bactericidal effect, which can kill bacterial propagules, fungi, protozoa and some viruses. Used as disinfectant in medical treatment. Alcohol is also generally used for disinfection, which has the function of promoting blood circulation and removing blood stasis. However, if you sprain your ankle, you can't immediately use blood circulation to remove blood stasis, so as to avoid more blood flow and swelling, because there are many capillary injuries around your ankle besides ligament injuries, causing bleeding and swelling.

1. After spraining your ankle, try to keep the injured foot still. If possible, it can be fixed with bandages, which can reduce the degree of swelling.

2. Massage should be avoided within 24 hours after injury, and the cold compress should be repeated 3~5 times, preferably every 2 hours 1 time. This is because the local capillaries are still broken within 24 hours after sprain. Cold compress can promote vasoconstriction, and some sprays can also be used to help stop bleeding and relieve pain.

After 3.24 hours, hot compress with warm water twice a day. Hot compress after 24 hours can promote blood circulation and remove blood stasis, and promote the absorption of blood stasis.

After spraining ankle, it is best to find a specialist in time to avoid future trouble.

Cold compress can reduce bleeding within 24 hours after injury, and hot compress can promote the absorption of congestion after 24 hours. It is suggested to take drugs for promoting blood circulation and removing blood stasis at the same time. Such as three or seven tablets. You can exercise your ankles properly.

If the pain is severe, there may be ligament damage. It is recommended to come to the hospital for orthopedic surgery. First, distinguish the severity of the injury. If you can stand with a load and barely walk after spraining your foot, it means that the sprain is light and you can handle it yourself; If the ankle is in severe pain after spraining the foot, and you can't stand or move, press the painful place on the bone and gradually swell, which means that you may have sprained the bone, and you should go to the hospital for a film immediately.

Correct use of hot compress and cold compress. At the beginning of the sprain, the broken small blood vessel was bleeding. At this time, you can use cold compress to make the blood vessels contract and coagulate, and control the development of the injury. After 24 hours, the bleeding of the ruptured blood vessel stopped. At this time, hot compress can be used to promote the dissipation of congestion around the sprain. Rational use of drugs. In the early stage of sprain, it is not necessary to take drugs orally, nor should it be used externally to promote blood circulation, so as to avoid excessive blood flow and swelling. After 24 hours, take some Yunnan Baiyao, Da Die Pill and Huoxue Zhitong Powder orally, so that there is no need for oral and external drugs after swelling.
