firstly i request you to stop any any kind of self medication
and self treatment, any unsterilized instrument induce infection which may lead to severe complications like septicaemia
i believe as per your symptoms its gum abscess/ or periapical abscess
they are mainly pus filled bumps caused due to infected tooth or gum.
kindly visit a dentist
for a personal examination of the problem, with investigative x ray to rule out exact daignosis. drainage of pus and an antibiotic +analgesic
course as prescribed by doctor.
till then you can rinse with half cup of Luke warm water + half tbs of salt in it, twice daily for 10 days.
NO HOT COMPRESS FROM OUTSIDE only warm saline rinsing is enough.
