Throat infections can affect your pharynx, tonsils and larynx (voice box). Since you have your tonsils removed it can not be tonsillitis
. If i was your doctor i would have liked to know about if your sore throat
affects your speaking or not. Secondly i would have liked to examine your throat and would have performed laryngoscopy
to rule out infection of larynx.
If you do not have any pain while speaking then it might be just infection of your pharynx that we call pharyngitis
. Its nothing to worry about. Still if i was your doctor i would have advised u to start antibiotics with nurofen
. Nurofen is just a pain relieving medicine. it wont help u much until n unless u start taking antibiotic with it too.
