Differential Diagnosis for Medial Feet Pain
Single Most Likely Diagnosis
- Plantar Fasciitis: This condition is the most common cause of heel and foot pain, including medial foot pain. It involves inflammation of the plantar fascia, a band of tissue that runs along the bottom of the foot, supporting the arch. The pain is typically worse in the morning and after periods of rest.
Other Likely Diagnoses
- Morton's Neuroma: A condition characterized by a thickening of the tissue around one of the nerves leading to the toes, often causing pain in the ball of the foot, which can radiate to the medial aspect.
- Medial Plantar Nerve Entrapment: Similar to Morton's neuroma but involves the medial plantar nerve, causing pain and numbness in the medial foot.
- Overuse or Stress Injuries: Including medial foot stress fractures or strains from repetitive activities or sudden changes in physical activity.
- Bunions (Hallux Valgus): A deformity of the big toe joint that can cause medial foot pain due to the abnormal positioning of the toe and the resultant pressure on the medial aspect of the foot.
Do Not Miss Diagnoses
- Deep Vein Thrombosis (DVT): Although less common, DVT can present with pain in the foot, including the medial aspect, and is a medical emergency due to the risk of pulmonary embolism.
- Infection (Cellulitis, Abscess): Infections in the foot can cause significant pain and have serious consequences if not treated promptly, including the potential for sepsis.
- Diabetic Foot Ulcer or Neuropathy: Individuals with diabetes are at risk for foot ulcers and neuropathy, which can cause pain, numbness, or tingling in the feet, including the medial aspect.
Rare Diagnoses
- Tarsal Tunnel Syndrome: A rare condition that involves compression of the posterior tibial nerve as it travels through the tarsal tunnel on the inner side of the ankle, causing pain, numbness, and tingling in the foot.
- Arthritis (Rheumatoid, Psoriatic, Gout): While more commonly affecting other joints, certain types of arthritis can cause pain in the feet, including the medial aspect.
- Bone Cysts or Tumors: Rarely, bone cysts or tumors in the foot can cause localized pain, including in the medial foot area.
