Ordinary acupuncture is ok, but if it is a relatively large needle, it will not work, and it is easy to be infected. Ankle sprain should be treated as soon as possible. After local muscle fascia injury, the symptoms will be gradually relieved by using some drugs to relax muscles and promote blood circulation. So it's ok to soak your feet. If you don't soak your feet, you can take some drugs to relax muscles and promote blood circulation orally, which will also have obvious effects, such as Sanqi tablets and so on.
