hello & welcome,
Abscessed molar extraction should always be carried out under the coverage of Antibiotics and absolutely after proper drainage of the pus. Otherwise infection may get aggravated.
In your case, you have written that last antibiotic was taken by you about 3 weeks ago & you have undergone extraction procedure just a 3 days before..! You should have taken prescribed dose of antibiotics before pulling out your tooth.
This is necessary especially with the teeth which are abscessed at the time of extraction.
Sweating can be expected as a result of fatigue or general dehydration
due to reduced food and water intake. It may occur in patients who are suffering from Hypertension
Get your blood examined for sugar level. Visit your dentist
immediately to rule out any chances of septicemia
which is spread of the infection from the extraction wound through blood.
Avoid random use of painkillers without dentist's consent as it may add to the problem. Drink plenty of water to cure dehydration if present. Eat high protein containing diet.
