When a toenail is bruised and swollen, it is important to rule out whether the bones of the patient’s toe have been injured. If there is no problem with the bones but bleeding under the skin, cold compresses can be used to relieve the bruise. Cold compresses can effectively constrict the local blood vessels within 24 hours of the formation of the bruise, reduce bleeding and prevent further expansion of the bruise area, and then change to hot compresses after 1-2 days to relieve local swelling, accelerate blood circulation and promote absorption and fading of the bruise. Patients can also take oral anti-inflammatory and pain-relieving medications and use topical medications such as Yunnan Baiyao spray to speed up the reduction of swelling. Patients should rest, elevate the foot as much as possible, and walk less to avoid aggravating the pain.
