Hello Welcome in H.C.M. I have gone through your query regarding white bumps in the back of your throat giving you pain, you are worried for it and your tonsils had been removed about 2 years back. After analysing your symptoms and co-relating them with the possible pathological process it appears as you are having acute pharyngitis with oropharyngeal ulcers covered with slough. This is a bacterial infection, and may be manage as- 1- Tab Paracetamol. 2- Warm saline gargling. 3- Antacids with PPI. 4- Antibiotics (preferably broad spectrum). 5- Adequate fluid orally. Most likely above will help you. Regards.
