Recurrent inflammation of the parotid gland over several years may be due to chronic (long-term) infection, blockage of the salivary duct, small salivary stones that are difficult to detect, autoimmune conditions, or chronic inflammation rather than an active abscess. Augmentin is commonly prescribed to treat bacterial infections, but improvement may sometimes take longer, and in some cases, antibiotics alone may not fully resolve the problem. Since you are already on the 5th day without improvement, it is important to continue the prescribed course unless your ENT doctor advises otherwise. Along with medicines, supportive measures such as drinking plenty of water, warm compresses, gentle gland massage, and sucking sugar-free sour candies or lemon drops may help stimulate saliva flow and reduce blockage. If your symptoms persist after completing treatment, your ENT doctor may consider further evaluation, such as an ultrasound, MRI, salivary duct examination, or tests for autoimmune diseases. In some chronic cases, procedures such as sialendoscopy may help open blocked ducts and reduce repeated inflammation. You should seek medical evaluation promptly if you develop a fever, severe pain, difficulty opening your mouth, pus discharge, or rapidly increasing swelling.
