Welcome in H.C.M.
I have gone through your query regarding Recurrent tonsillitis
with whitish spots over tonsils and yellowish material comes out of it.
Your history of illness indicated that most likely you are suffering from chronic tonsillitis
The yellowish particles comming out are organised pus. Usually such cases are cured by tonsillectomy
only.So my advive is to consult your ENT doctor for thorough examination and treatment as to avoid complications of disease.
