Many organisms (viral and bacterial) can cause a sore throat or pharyngitis; most acute pharyngitis infection is due to a virus. Strep pharyngitis, however, is due to a bacteria and is treated with an antibiotic to prevent negative sequela.
Your tonsils are apart of your immune system; they are two lymph nodes which can become inflamed and enlarged with infection. During a tonsillectomy, tonsils are removed; however, some tonsillar tissue may still remain and over time, it is possible for tonsillar tissue to "regrow" or regenerate.
If you are experiencing a worsening sore throat with or without exudate, especially, if you are experiencing a persistent fever and/or decrease fluid intake, then it is strongly recommend that you are seen and evaluated by your physician as soon as possible.

It is a good idea to see your pediatrician to develop a program that

What is concerning about your question is that your 8 year old "suddenly

child to his/her pediatrician for an evaluation. Has there been a change
and/or new stressors in your child's environment at home or school? Or
there any other symptoms that your child is experiencing? These are
questions that can be addressed with a visit with your pediatrician.
