Welcome in H.C.M.
I read your query regarding pain in chest and throat during swallowing on right side of throat and you off and on also feels sharp pain
in the ear of same side (right).
Your symptoms are in fovour of right sided tonsillitis
, though unilateral tonsillitis is rare and is found in cases of tonsillar cyst
and quiency. Such tonsillar pain more often give rise to referred pain
in ear of same side as you are having.
To manage it a thorough examination of throat and ear is necessary therefore I supposed here consultation with ENT doctor is necessary as to avoid further complications.
