Hello and thank your for using HCM for your health questions!
It seems to me that you are suffering from
tonsillitis, that is the infection of the tonsils. Probably it is bacterial tonsillitis, caused by
streptococcus, etc. It can be also caused by viruses.
It is possible that the infection has progressed and your tonsils have become purulent, with pus developing on them, visible by naked eye. In these cases tonsils become very painful and it is very painful to even open your mouth or swallow own saliva, not talking about drinking water or eating anything!
The
high fever and
incubation period supports this diagnosis.
In this case you need to be treated urgently by antibiotics, by going to your family physician. If there is pus on your tonsils then you might need to take an intro-venous (i.v) antibiotic such as zinnat (
cefuroxime) or other antibiotics that will by suggested by your doctor.
Please hurry up to be treated because if the pus escalates into abscess then you will need to remove your tonsils.
I hope that my answer will help you and I wish you fast recovery!
