Symptoms of pain and pressure in the submandibular gland are most often seen in patients with submandibular adenitis. Submandibular adenitis is often complicated by salpingolithiasis and is most common in young adults, more often in men than women, with a short history of a few days or a long history of several years or more. There are two types of submandibular adenitis: acute and chronic, with chronic submandibular adenitis being the most common clinical condition. The pain and pressure in the submandibular gland caused by submandibular adenitis seriously affects the quality of life of patients, and early diagnosis can help the treatment and recovery of the disease. So, how to diagnose submandibular gland pain and pressure pain? Here’s what you need to know. The diagnosis of submaxillary gland pain and pressure pain: 1. Diagnostic points (1) Submaxillary adenitis is mostly chronic, but can also be acute. Acute submandibular adenitis is a symptom of general acute inflammation, with painful swelling at the floor of the patient’s mouth and redness at the submandibular triangle. The submandibular ducts are red and swollen, and there is pus or inflammatory fluid flow from the submandibular glands when they are pressed. Systemic symptoms are fever, rapid respiration and pulse rate, and increased total white blood cell count and neutrophils. (2) Patients may have recurrent acute attacks that may turn chronic. On palpation, hard stones can sometimes be found in the ducts of the submandibular gland, and positive stones can sometimes be found on X-ray. 2. Diagnostic tests (1) Ask if there is any chronic pain in the submandibular area, whether the local mass is large or small, whether there is swelling when eating, and how effective the antibiotic medication is. (2) Squeeze the submandibular gland to see if there is any purulent discharge from the mouth of the duct. (3) Palpate with both hands inside and outside the mouth for stones and whether the submandibular gland is enlarged and hardened. X-ray occlusion films can be taken if necessary.
