The accessory navicular bone is estimated to be present in around 20 percent of the population. While only those with the accessory navicular bone can suffer from this syndrome, the bone itself typically doesn’t cause any problems. However, there are times when the bone can become too large and can cause you to experience high amounts of pain until the problem is effectively treated. This condition also occurs whenever the bone is irritated or aggravated in any way. A few of the main reasons that you could become affected by this syndrome include:
People who suffer from flat feet have a higher risk of developing this condition than anyone else. When your foot doesn’t have the proper arch that it should, exercising and walking will invariably place more strain on the accessory navicular bone, which can cause the bone to become inflamed or irritated.
Since the bone that can lead to the accessory navicular syndrome is present at birth, the condition can start to develop at any time. Many people begin to experience symptoms pertaining to this syndrome during adolescence. It’s at this time your bones begin to properly mature. While it’s common for adolescents to experience these symptoms, you may not experience them yourself until you’ve reached adulthood.
If you’re beginning to suffer from this syndrome, you’ll notice a bony protrusion along the inner portion of your foot that’s situated right above the arch. This protrusion will become red and swollen over time. While the pain that you go through can be a sharp pain, it’s more commonly going to be dull and aching around the middle area of your foot. The pain usually occurs during or following lengthy activity, which means that the pain can flare up while you’re exercising, or just afterwards.
As is the case with most foot conditions, the best way to diagnose accessory navicular syndrome is through a physical examination at a doctor’s office. The doctor or ankle surgeon will examine your foot and ask about any symptoms that you’re experiencing. While conducting the examination, they will primarily be looking for any swelling or skin irritation around the location of the bone. It’s likely that a small amount of pressure will be placed on the bone to determine the amount of discomfort that you’re going through.
Your muscle strength, foot structure, and motion of the joints will also be evaluated. In many cases, an x-ray or similar imaging test will be administered as a means of confirming the diagnosis of accessory navicular syndrome. If you’re experiencing severe pain along with the inflammation, it’s possible for more comprehensive tests to be provided.
