Many people have experienced oral ulcers, sometimes accidentally biting their mouth, which can turn into oral ulcers in a few days. Oral ulcer disease is prone to recurrence, and many patients with severe oral ulcers often cannot eat normally, which has a significant impact on their daily lives. Next, what are the symptoms of oral ulcers in the encyclopedia?
1. Mild oral ulcer
At the beginning of the lesion, there may be a sensitive or slightly larger congested area resembling a needle tip. In a short period of time, a shallow ulcer with a diameter of about 2-4mm, circular or elliptical, and clear boundaries may form. The center is slightly depressed, and the surface is covered with a light yellow pseudomembrane. The mucosa around the ulcer is congested and appears as a red halo, and the base is not hard. The number of ulcers is generally about 2-3. After ulcer formation, there is a severe burning pain, especially at the tip of the tongue, which is more severe when exposed to irritating food. Generally, there are no systemic symptoms.
2. Herpetic oral ulcer
Also known as inflammatory mouth ulcers, this type of ulcer is similar to mild mouth ulcers in appearance, except for small and numerous ulcers (up to 20-30). Ulcers are scattered, widely distributed, with obvious mucosal congestion, severe pain accompanied by headache, fever, local lymph node enlargement, and other symptoms.
3. Periglandular oral ulcer
Also known as recurrent necrotizing mucositis or giant oral ulcers, it is the most severe type among all types. Ulcers often occur individually, and two or more are rare. They are more common in the mucosa of the inner lip and corner of the mouth, and can also occur in the tongue and palate arch, soft palate, and other areas. At the beginning, ulcers are the same as mild oral ulcers, but their diameter gradually expands to 1-2cm and develops to the mucosal glands. Ulcers are purple red or dark red, with irregular edges, petal like protrusions, central depression, resembling "bullet holes", uneven bottom, slightly hard, and small nodular shape. The redness around the ulcer is obvious, and there is severe pain locally, which may be accompanied by systemic symptoms such as local lymph node enlargement and fever. The course of the disease often lasts for more than a month, and in the elderly it can take up to a year. Scars may be left after healing, and in severe cases, tissue defects or deformities may form.
4. Behcet's syndrome
Also known as the eye mouth genital triad, this disease is a systemic disease characterized by recurrent oral, skin, genital, and eye damage, and can also affect joints, cardiovascular, and nervous systems.
