If you have a bruised toe or toenail from an accident while doing physical activity, running, or from a blunt injury, there are ways to help the healing process. Treat swelling and pain for the first few days after being injured. Use natural remedies and other techniques to promote healing and prevent infection, especially if the bruise is below a toenail. If your foot doesn't seem to get better after a few weeks, go to your doctor for an exam. Most toe injuries, even fractures, will heal within six weeks, depending on the severity of the injury.
