Welcome to healthcare Magic!
You have got a bad sore throat
and that is the sorce of the bleed, local swelling and the enlarged lymphnode also tell the same story.
You have already been examined by the ENT docyor, so malignancy does not seem to be a cause.
You should start an antibiotic like Augmentin
in supervision of a clinician.
You should improve the oral health, brush twice a day and do chlorhexidine
mouth gargles thrice a day and avoid eating any edibles during ensuing 2 hours to ensure good germicidal effect of chlorhexidine; Do warm saline gargles after you take anything orally.
I hope the advise would be informative and useful for you.
