It appears that your doc thinks you have a throat infection with a reaction from the related lymph nodes and so prescribed you antibiotics. Waldeyer's tonsillar ring is an anatomical term describing the lymphoid tissue ring located in the pharynx, thought to be a barrier to infection. The ring consists of:
- Adenoids (also termed pharyngeal tonsils)
- Tubal tonsils
- Palatine tonsils (more commonly termed "the tonsils"
- Lingual tonsils
See your doctor again if it doesn't improve after your course of antibiotics. Let us know how you get on.
