My feet burn and sting sometimes. It almost feels like lots of flea bits on the top of my foot. What could this be?
There are many things that can cause pain on the top of the foot, including nerve damage, bone spurs, stress fractures, and tendonitis. The only way to really know what's causing the problem is to ask a doctor. If you haven't injured your foot and if it's happening on both feet I'd imagine it's probably something that needs to be diagnosed by a physician.
If you've found that the pain is interfering with your daily life these articles may help, but do get to a doctor when you can.
