If one ankle is swollen and one foot is not, you can take the following types of drugs: Firstly, if the ankle swelling is caused by trauma, you should take Cao Wu Jia Su tablets, Pan Long Qi tablets and Hu Li San capsules orally. All the above drugs can clear the meridians, eliminate the swelling caused by trauma and relieve the painful symptoms, and the effect is usually obvious for about two weeks continuously taken orally. Secondly, if the ankle swelling is caused by non-traumatic factors, such as osteoarthritis, synovitis and other diseases, oral administration of celecoxib capsule, loxoprofen sodium, mai zhi ling, wilithan and other drugs are needed, which can eliminate inflammation and relieve swelling symptoms. In addition to oral medication, patients also need to elevate the affected limb continuously and perform functional exercises to actively contract the muscles around the ankle to promote the swelling to subside. Early treatment can make the clinical symptoms get complete relief soon and make the condition recover completely as soon as possible.
