Parotid duct obstruction is when part of your parotid duct becomes blocked. The parotid ducts are 2 small tubes that lead from the parotid glands. These glands make saliva and send it into your mouth. When the parotid ducts are blocked, saliva can’t flow normally.
Sore throats happen for many reasons, such as colds, allergies, and infections caused by viruses or bacteria. Your goal for self-care is to reduce your discomfort while giving your throat a chance to heal.
