Long lasting sore throat can be from Mono. That throat may need antibiotics because "Mono throat" often develops a mixed infection.
It can also be Thrush, which is Candida. That would require an antifungal medicine.
It is not wise to let a sore throat go on this long. The bacteria can spread all over your body that way. It can spread to your thyroid too.
I hope you get your diagnosis soon!
