Hello and Welcome to Ask A Doctor service. I have reviewed your query and here is my advice.  White bumps on the tongue can be due to inflamed tongue papillae secondary to infection while it can also be due to canker sores or cold sores due to viral infection. So you should get a clinical examination done to rule out the exact cause of white bumps. Also, a blood test can be done to rule out the nature of infection.  If the bumps are painful you can apply Lidocaine gel but in very less quantity only over the bumps. Give him soft and bland foods. Hope I have answered your query. Let me know if I can assist you further.
