Tongue swelling, particularly when it occurs unexpectedly and is accompanied by symptoms such as bruising, blisters, and bleeding, can be concerning and may indicate underlying issues that warrant further investigation. The symptoms you describe, including the swelling being more pronounced on one side, the presence of red and black spots, and the tendency for the tongue to bleed, could be associated with several conditions that fall under the domain of ear, nose, and throat (ENT) disorders.

One possible explanation for your symptoms could be allergic reactions. Allergies to certain foods, medications, or environmental factors can lead to localized swelling of the tongue, known as angioedema. This condition can cause the tongue to swell significantly, sometimes to the point of discomfort or difficulty in speaking and swallowing. The presence of blisters or spots could also suggest an allergic response or irritation.

Another potential cause could be oral infections. Conditions such as oral thrush (a fungal infection) or herpes simplex virus can lead to swelling, pain, and the formation of blisters on the tongue. These infections can cause the tongue to feel hard or swollen, and they may be accompanied by other symptoms such as a burning sensation or difficulty swallowing.

Trauma or irritation is another consideration. If you have a habit of biting your tongue or if you consume very hot or spicy foods, this could lead to localized swelling and the formation of blisters. Additionally, if you are prone to picking at the blisters, this can cause bleeding and further irritation.

Vitamin deficiencies, particularly deficiencies in B vitamins (such as B12, folate, or riboflavin), can also lead to changes in the tongue's appearance, including swelling and soreness. A deficiency in iron can lead to a condition known as glossitis, which is characterized by a swollen, smooth tongue that may appear red and inflamed.

Autoimmune conditions such as lichen planus or pemphigus vulgaris can also cause symptoms similar to what you are experiencing. These conditions can lead to painful lesions, swelling, and changes in the texture of the tongue.

Given the complexity of your symptoms and their potential implications, it is crucial to consult with an ENT specialist or a healthcare provider who can perform a thorough examination. They may recommend diagnostic tests such as blood tests to check for allergies, vitamin deficiencies, or autoimmune markers, as well as imaging studies if necessary.

In the meantime, it may be helpful to keep a diary of your symptoms, noting any potential triggers such as specific foods, medications, or environmental factors. This information can be invaluable for your healthcare provider in determining the underlying cause of your tongue swelling.

In summary, tongue swelling can arise from a variety of causes, including allergic reactions, infections, trauma, nutritional deficiencies, and autoimmune disorders. A comprehensive evaluation by a medical professional is essential to identify the specific cause and develop an appropriate treatment plan.
