Most cases of foot pain are nothing serious and usually go away on their own without any medical treatment.
Foot pain can be caused by a variety of different things such as standing on your feet too long, running too long, walking too far, hiking or stepping on something that causes the foot pain.
However foot pain can also be caused by diabetes especially if the foot pain persists longer than a few days, comes back too often or gets worse.
If during the foot pain you experience any swelling, severe pain or have open wounds that are not healing then see a doctor.
If your foot becomes infected you need to see a doctor about the foot pain.
Some signs that your foot has become infected are redness, warmth and tenderness in the affected area or you have a fever over 100 F.
