Sunken forefoot (metatarsalgia) is an overload in the forefoot, which can cause painful discomfort in the worst cases. The condition is also known as flat forefoot or forefoot collapse.
Naturally, we have a small arch across the forefoot. This arch helps provide a springy push-off when we walk and run. If this arch collapses, the push-off becomes harder (the fat tissue in the ball of the foot disappears) and will put direct pressure on the metatarsal heads.
The pain typically occurs during activity, under load, and at night. It can be accompanied by swelling, slight warmth, and redness.
Typical symptoms:
- Forefoot pain
- Calluses on the middle section of the ball of the foot
- Numbness in the foot
- The entire midfoot may have collapsed, creating flatfoot
- Tingling toes
- Hammer toes
