Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain it seems that you have an inflammation in throat secondary to infection causing Pharyngitis and it is leading to swollen tonsils causing Tonsillitis.. It can be either due to bacterial or viral throat infection.. But in case if you are also coughing mucous it can be due to upper respiratory tract infection that can be viral in nature. I would suggest you to consult an Otolaryngologist and get evaluated and a throat swab culture can help in diagnosis and treatment can be done accordingly.. As of now you can start with supportive treatment to relieve the symptoms like: -Gargle with a warm saline solution that is by mixing 1 teaspoon salt in a glass of water and warm it to make a luke warm solution.. -Take a combination of decongestant like Phenylephrine, mucolytic like Ambroxol and anti allergic levocetrizine and another combination of Acetaminophen and Ibuprofen.. -Take cough expectorant containing Gueifenesin and cough suppressant containing Dextromethorphan. -Chew a Vitamin C pellet daily.. -Do steam inhalations.. -Avoid spicy and chilled foods.. -Sip on warm water throughout the day.. -Do warm compresses over chest.. Hopefully the symptoms will resolve within a week and if it worsen consult a General Physician and get evaluated.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
