Accessory navicular pain is commonly characterized as a vague or throbbing discomfort located in the midfoot and arch of the foot, often experienced during or after physical activity.
Understanding the Sensation
The pain associated with an accessory navicular bone is typically not sharp or sudden but rather a dull ache that can feel like a deep throbbing. This sensation can be persistent and particularly noticeable after the foot has been under stress.
Common Pain Location
The primary site of pain is the midfoot, specifically on the inner side of the foot, just above the arch. This area corresponds to where the accessory navicular bone is located. The discomfort often radiates into the main arch of the foot.
Triggers and Timing of Pain
Pain from an accessory navicular typically arises:
- During periods of activity: This includes sports, running, or even extensive walking.
- After periods of activity: The pain can linger or become more pronounced once the activity has ceased, as the inflamed tissues continue to react to the stress.
Activities that commonly trigger or worsen the pain include:
- Prolonged standing or walking
- Running or jogging
- Participation in sports that involve repetitive foot movements or impact, such as basketball or soccer
- Wearing unsupportive footwear that does not properly cushion or support the arch
Associated Visible Signs
Beyond the internal feeling of pain, accessory navicular syndrome often presents with observable physical signs around the affected area:
- Visible Bony Prominence: A distinct, noticeable bump or bony protuberance on the inner side of the midfoot, just above the arch. This is the accessory navicular bone itself.
- Redness: The skin over the bony prominence may appear red.
- Swelling: There might be noticeable swelling around the bony prominence, indicating inflammation of the surrounding soft tissues, such as the posterior tibial tendon that attaches to this area.
