hi thank you for the query I have gone through your query and understood your concerns... after going through your query enlarged tonsils ,glads in the neck lesions on uvula and coughing out thick green mucus with rattling along with som ulcers on lip I can give few possibilities with my knowledge bronchitis acute purulent tonsillitis and pneumonia.. if you do have any constitutional symptoms like fever , malaise anorexia.. throat pain ...I would suggest you to see the doctor and get a thorough examination of your upper respiratory tract. for that I would suggest you to see a ENT specialist ..get a chest X -ray done and run some blood works... anti biotics and decongestants would help you to get back your voice and resolving of the swellings in your neck ..one thing I would like to suggest you if you don t get offended, maintain proper oral hygiene under your dentist guidance hope I have answered your query thank you regards DR Alekhya
