Morton neuroma and intermetatarsal bursitis can cause forefoot pain, burning, tingling or a pebble-like sensation under the ball of the foot. Symptoms are often worse in tight shoes or with prolonged walking.
Morton neuroma describes irritation and thickening around a nerve between the metatarsal bones in the forefoot. Intermetatarsal bursitis can produce similar symptoms and may coexist. Patients often describe burning, tingling, numbness or a feeling of walking on a small pebble.
Assessment considers footwear, foot shape, activity load, tenderness between the metatarsals and whether symptoms are nerve-like. Ultrasound can be useful when the diagnosis is uncertain or an image-guided procedure is being planned.
Non-surgical care usually begins with reducing compression through the forefoot. This may involve wider shoes, metatarsal support, load modification and addressing training or work demands. Persistent symptoms may warrant discussion of injection options and, in selected cases, surgical referral.
