Differential Diagnosis for Feet Arch Pain
- Single most likely diagnosis
- Plantar fasciitis: This is the most common cause of arch pain, resulting from inflammation of the plantar fascia, a band of tissue that supports the arch of the foot. Overuse, poor foot mechanics, and inadequate footwear are common contributing factors.
- Other Likely diagnoses
- Flat feet (pes planus): A condition where the arch of the foot collapses, leading to strain on the muscles and ligaments that support the arch, causing pain.
- Overuse or repetitive strain injuries: Activities that involve running, dancing, or jumping can lead to arch pain due to repeated stress on the foot.
- Poorly fitting shoes: Shoes that do not provide adequate arch support or are too tight can cause arch pain.
- Achilles tendonitis: Inflammation of the Achilles tendon, which connects the calf muscles to the heel bone, can cause pain in the arch area.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Deep vein thrombosis (DVT): Although rare, DVT can cause foot pain, including arch pain, and is a medical emergency due to the risk of pulmonary embolism.
- Osteomyelitis: A bone infection that can cause severe pain, including in the arch of the foot, and requires prompt antibiotic treatment.
- Tarsal tunnel syndrome: Compression of the posterior tibial nerve can cause pain, numbness, and tingling in the foot, including the arch.
- Rare diagnoses
- Rheumatoid arthritis: An autoimmune disorder that can cause inflammation and pain in the feet, including the arch.
- Gout: A form of arthritis characterized by sudden, severe attacks of pain, swelling, redness, and tenderness, often in the big toe, but can also affect the arch.
- Stress fractures: Small cracks in the bones of the foot, which can cause pain in the arch area, especially with weight-bearing activities.
