Thanks for writing to H.C.M.for your query.
I have gone through your query regarding recurrent tonsillitis
and now you have developed off and on ear blockade.
Here I would like to tell you that due to tonsillitis your throat is infected and the pharyngeal end of eustachian tube gets infected and blocked thus your middle ear suffers as far as ventilation is concern therfore ear gets blocked.
operation your this problem ( recurrent ear blockade) will also besolve.
