What are the possible causes of a swollen and bumpy tongue, often referred to as strawberry tongue?

### What is Strawberry Tongue? Strawberry tongue is a term used to describe a tongue that is swollen, red, and bumpy. It is not a condition itself but a symptom of various underlying conditions or disorders. The tongue usually appears red, but it can also appear white in some cases. Another term for this condition is raspberry tongue. ### Possible Causes Strawberry tongue can be a symptom of several different conditions, including: 1. **Scarlet Fever**: A bacterial infection that can cause a red, bumpy tongue. 2. **Kawasaki Disease**: A condition that affects children and can cause inflammation in the blood vessels, leading to a strawberry tongue. 3. **Toxic Shock Syndrome**: A rare but serious condition caused by bacterial toxins that can result in a red, swollen tongue. 4. **Vitamin Deficiencies**: Low levels of certain vitamins, such as B12, can lead to changes in the tongue's appearance. 5. **Allergic Reactions**: Allergies to foods or medications can sometimes cause the tongue to swell and become bumpy. ### Similar Conditions A condition similar to strawberry tongue is glossitis, which also causes the tongue to become swollen and red but not bumpy. Like strawberry tongue, glossitis can be a symptom of various underlying conditions, including vitamin deficiencies. ### When to See a Doctor If you notice that your tongue is swollen and bumpy, it's important to consult a healthcare provider to determine the underlying cause. Early diagnosis and treatment can help manage the symptoms and address the root cause effectively.
