hello and welcome to HCM,
I have understood your problems regarding sore throat
and the thing hanging from the tonsil.
You seem to be having a combination of acute pharyngitis
along with reflux.
The treatment is with an antibiotic like amoxycillin-clavulanate
625 mg combination and pantoprazole
40 mg for five days and two weeks respectively. Your doctor will know about these.
The thing hanging from your tonsil could be either a tonsil stone which we call the tonsillolith
or if between the tonsils could be an enlarged uvula. Both these should get better with the above treatment.
You should also avoid oily and spicy food and do not strain.
If you are not getting better then you should get and upper GI endoscopy and get back to me with the report.
Take care and get well soon
Dr Sriram Nathan
