Differential Diagnosis for Pain Under Both Feet
Single Most Likely Diagnosis
- Plantar Fasciitis: This condition is characterized by inflammation of the plantar fascia, a band of tissue that runs along the bottom of the foot. It is a common cause of pain under the feet, especially after periods of rest or activity. The pain is typically worse in the morning and improves with movement.
Other Likely Diagnoses
- Overuse or Repetitive Strain Injury: Activities that involve repetitive stress on the feet, such as running or standing for long periods, can lead to pain under the feet due to strain on the muscles and ligaments.
- Poor Footwear: Wearing shoes that do not fit properly or provide inadequate support can lead to pain under the feet due to abnormal distribution of pressure.
- Morton's Neuroma: A condition where a nerve in the foot becomes irritated or compressed, leading to pain between the toes or under the foot.
- Flat Feet or Fallen Arches: Conditions where the arch of the foot collapses, leading to altered biomechanics and potential pain under the feet.
Do Not Miss Diagnoses
- Diabetic Neuropathy: A complication of diabetes that can cause nerve damage, leading to pain, numbness, or tingling in the feet. It is crucial to identify and manage this condition to prevent further complications.
- Peripheral Artery Disease (PAD): A condition where the arteries that supply blood to the feet become narrowed, leading to pain in the feet or legs during activity. PAD can lead to severe complications, including gangrene and amputation, if not addressed.
- Infection (e.g., Cellulitis or Osteomyelitis): Infections of the skin or bone in the feet can cause severe pain and have serious consequences if not promptly treated with antibiotics.
Rare Diagnoses
- Tarsal Tunnel Syndrome: A condition similar to carpal tunnel syndrome but affecting the nerves in the ankle, leading to pain, numbness, or tingling in the foot.
- Paget's Disease of Bone: A rare condition that can affect the bones in the feet, leading to pain and deformity.
- Reflex Sympathetic Dystrophy (RSD) or Complex Regional Pain Syndrome (CRPS): A chronic pain condition characterized by severe, burning pain in the feet, often following an injury or trauma.
