I am an orthopedic surgeon. Like you, I like playing basketball very much. I sprained my ankle badly when I stepped on someone else's instep, but the fastest time was when I happened to play in the hospital. Immediately after the injury, use ice packs 1 hour to contract blood vessels, so as to prevent bleeding of sprained ligaments and other soft tissues, resulting in congestion and swelling of ankles. After 24 hours, soak your ankle with hot water to speed up blood circulation and let the congestion dissipate as soon as possible! Then use gold powder (available in Chinese medicine hospital) for external application, or use Yunnan Baiyao (with all the points) to spray several times a day! After the injury, use elastic bandage (available in sports specialty stores) or homemade bandage to protect your ankle! It is best not to lie prone on the ground, and put a pillow on the heel of the affected foot when sleeping at night, which is beneficial to venous return and eliminate bruising as soon as possible! At that time, I thought it would take me at least two months to touch the ball, but I didn't expect to return to the court in only three days! In your case, you didn't apply cold compress immediately, which led to bruises on your ankles. The urgent task now is to reduce swelling, hot compress, spray medicine and protect feet (reduce ankle activity). Normal outdoor activities range from 3 days to 5 days! Everything I said is after you are sure that the triangular ligament has not been torn. When you encounter a sprain in your life, you must remember: cold compress first, and hot compress after 24 hours! Every step is important! Wish you an early back in the game!
