Ankle sprain will not be a big problem as long as it doesn't hurt the muscles and bones, but it will take a long time to raise it. The reason why your left foot can't bend up normally is that there is bleeding and tissue edema in the injured part after sprain, which affects joint function. As long as you rest for a while and treat it in the following ways, you will get better soon.

1. The main purpose of raising the affected limb is to reduce swelling and promote blood return.

2. You can massage the hot compress and slowly start to resume exercise and stretching. Be sure to warm up before exercising and stretching.

3. The medicated wine for external use is mainly used for treating motor system injury. When in use, the medicated wine is first applied to the affected part, and then repeatedly pressed, rubbed and caressed around the affected part, supplemented by rubbing, poking, sliding and turning, so as to improve the curative effect.

4. Massage therapy. After 3 days, you can have a light massage: (1) massage Jiexi point (between extensor pollicis longus tendon and extensor digitorum longus tendon)1min; (2) Massage Kunlun point (the midpoint of the connecting line between the lateral ankle and achilles tendon)1min; (3) Massage hanging hours (3 inches above and below the lateral ankle tip and the posterior margin of fibula)1min; (4) Massage Yanglingquan point (the depression below fibular capitulum) 1min. The above acupoint massage is carried out according to the patient's feeling of acid swelling.

5. Acupuncture treatment of ankle sprain. When the patient takes a supine position or a sitting position, the doctor will massage the ankle, first from the affected part to the surrounding area, then from the lateral ankle, and then from the lateral leg to the Xiangyang Lingquan, focusing on Xu Qiu, Jueyin and Yanglingquan. Then push the affected area with your thumb, which is also from local to all around to promote blood circulation and remove blood stasis.
