177. Baxter’s Nerve: The Overlooked Cause of Chronic Medial Heel Pain

Send us Fan Mail

In this PT Snacks episode, host Kasey introduces Baxter’s nerve (the first branch of the lateral plantar nerve, also called the inferior/anterior calcaneal nerve) as an under-recognized source of medial plantar heel pain that can mimic plantar fasciitis and may account for up to 20% of chronic heel pain. We review the nerve’s motor and sensory roles, common entrapment zones near the distal tarsal tunnel and medial calcaneal tuberosity, and typical presentation including burning neuropathic pain, possible paresthesia, focal tenderness, and potential abductor digiti minimi weakness or atrophy. This episode outlines key differentials, relevant imaging and testing findings (ultrasound, MRI, EMG/NCS), and a treatment progressions.
