I Have Been Having A Problem With A Sore Throat
Most likely symptoms that follow an inflammation.
Hello and welcome to "Ask A Doctor" service.
I have read your query.
Since the left tonsil was removed and you had fever previously, it is likely that the muscle you are referring to was affected by the adjacent inflammation.
Clicking sound in the ear as you breathe may be also linked to a previous throat infection that may have spread into the Eustachian tube.
I don't see any neurological conditions that may cause such issues... So, in my opinion, you should continue following up with your ENT Doctor.
I hope you found the answer helpful.
Feel free to ask if you have further questions.
