Differential Diagnosis for Pebble Sensation Bottom of Foot
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. The pebble sensation could be due to the formation of a heel spur or the thickening of the plantar fascia, which can cause discomfort and a sensation of walking on pebbles.
Other Likely Diagnoses
- Morton's neuroma: A condition where a nerve in the foot becomes irritated or compressed, leading to pain, numbness, and a sensation of walking on a pebble.
- Foot callus or corn: Thickened skin on the bottom of the foot can cause discomfort and a sensation similar to walking on pebbles.
- Bunion or bunionette: A bony growth on the joint of the big toe or little toe can cause pain and discomfort, potentially leading to a pebble-like sensation.
Do Not Miss Diagnoses
- Deep vein thrombosis (DVT): Although less common, DVT can cause swelling, pain, and discomfort in the foot, which might be misinterpreted as a pebble sensation. Missing this diagnosis could be life-threatening due to the risk of pulmonary embolism.
- Peripheral artery disease (PAD): Reduced blood flow to the feet can cause pain, numbness, and tingling, potentially leading to a sensation of walking on pebbles. PAD is a serious condition that requires prompt medical attention.
Rare Diagnoses
- Tarsal tunnel syndrome: A rare condition where the posterior tibial nerve is compressed, leading to pain, numbness, and tingling in the foot.
- Foreign body in the foot: Although rare, a small object like a splinter or a piece of glass can become embedded in the foot, causing pain and a sensation similar to walking on pebbles.
- Neurological disorders: Certain conditions like peripheral neuropathy or Charcot-Marie-Tooth disease can cause abnormal sensations in the feet, including a pebble-like feeling.
