Differential Diagnosis for Tongue Pain on the Left

- Trauma or minor injury to the tongue: This is often due to accidental biting of the tongue, eating hot or sharp foods, or other minor mishaps that can cause pain on one side of the tongue.
- Other Likely diagnoses
- Dental issues: Problems such as a cavity, abscess, or gum disease on the left side of the mouth can radiate pain to the tongue.
- Oral ulcers or canker sores: These can develop on the tongue and cause localized pain, especially if they are on the left side.
- Nutritional deficiencies: Deficiencies in vitamins like B12 or iron can cause changes in the tongue, including pain.
- Allergic reactions or irritations: Certain foods, substances, or oral care products can cause an allergic reaction or irritation leading to tongue pain.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed)
- Oral cancer: Although less common, cancer of the tongue can present with pain, especially if it's localized to one area. Early detection is crucial.
- Neurological conditions: Conditions affecting the nerves, such as trigeminal neuralgia, can cause severe, stabbing pain in the face and tongue.
- Infections: Severe infections, including abscesses or cellulitis, can cause significant pain and have serious consequences if not treated promptly.
- Rare diagnoses
- Geographic tongue: A condition characterized by the appearance of single or multiple, well-demarcated areas of depapillation on the tongue surface, which can sometimes cause discomfort or pain.
- Median rhomboid glossitis: A rare condition that presents as a smooth, red, flat, or slightly raised area on the central posterior part of the tongue, which can be painful.
- Erythema multiforme: A skin condition that can also affect the mucous membranes, including the tongue, causing pain and ulcers.
