Hi, i have had some type of novocaine for fillings, the first filling done on upper right, 2 days later tremendous pain in my teeth on left side, asked the dentist, he didn't have a clue, a week later filled cavity on lower right, same occurrence,(on left side) a week later cavity on upper left, 2 days later extreme pain, mostly in bottom left, every tooth was like nerves on fire, now the teeth on upper left hurting, but not as much, but face swelling much more. pain is intense. Thank you for any information, also my throat on left side seemed too close, have been feeling nauseous, but i think from pain.
