It is not possible to generalize whether a swollen foot can heal on its own. A mildly broken and swollen foot may heal on its own after outside intervention is given. But in serious cases, due to local soft tissue injury after exudation, edema, can lead to local swelling, aseptic inflammation, and even cause capillary rupture bleeding, hematoma, can not be self-healing, patients should go to the hospital in a timely manner to clarify the injury after active treatment. 1, minor broken injury swelling: pain symptoms are light, and local swelling is not serious, can be carried out within 24 hours ice bags or ice towels cold compress, to avoid capillary expansion congestion and local sterile inflammation The affected limb can be elevated to reduce local blood circulation. After 48 hours, hot compress can be applied to promote blood circulation and swelling absorption recovery; 2. Severe sprain swelling: severe sprain can lead to local vascular rupture, ligament strain or even tear, often causing severe pain and obvious subcutaneous swelling or hematoma, so that the patient’s activities are limited, at this time, fracture can also be considered, usually can not be self-healing, should immediately go to the hospital for medical consultation. In addition to rest, hot and cold compresses, oral pain medication such as ibuprofen, meloxicam, or topical flurbiprofen gel paste can be used to relieve pain as prescribed by the doctor. Patients need to further improve the X-ray examination to clarify whether the fracture occurred, and consider giving treatment such as manual repositioning, internal fixation or external fixation. Patients with swollen feet are advised to go to the hospital in a timely manner. If patients are reluctant to seek treatment, it may cause continuous damage to the ligaments or other soft tissues in the joint. The foot is a frequently active part of the body, which may stimulate the recurrence of sterile inflammation, affecting the patient’s life while possibly even leading to osteoarthritis, and should therefore be treated actively at the early stage of the injury.
