A bump, lump, and knot on top of your foot can be caused by a number of reasons. One common cause is a bone spur. There are other bumps that are because of soft tissue flare-ups such as a bursa or cyst. You my think that a painful bursa or cyst on top of the foot would be quick and easy to treat, but think again.
A bursa is a fluid-filled sack that your body creates in response to pressure. The pressure may be external, such as a tight shoe, or may be because of pressure caused by a bone spur beneath it. It contains a thin, watery fluid but you can't pop it like you may do with a blister. With continued pressure, the tissue will inflame and is known as a bursitis.
A cyst, such as a ganglion cyst, is also a soft tissue sack that fills with fluid. These occur deeper in the foot, often involving a tendon, and is filled with a much thicker, viscous fluid. This thick fluid makes it more difficult to drain.
In my Houston podiatry office focusing on painful bumps, lumps, and knots on your foot, I will identify what the bump is and, if appropriate, drain the cyst or bursa. At that point your body may or may not cause it to return. There are measures we can take to try to prevent it from returning. For instance, using cortisone in the bump after it is drained and using a compressive dressing will help to prevent it.
There are times where draining isn't enough. Sometimes a cyst or underlying bone spur needs to be removed with foot surgery. Other times it just takes repeatedly draining and modifying the pressure from the shoes. Either way, Houston podiatrist Dr. Andrew Schneider will evaluate the bump, lump, or knot on top of your foot and advise you about the best treatment.
