ok so i just had a root canal, everyone told me not to, to just get it pulled because they always get infected, well i need 2 more, the root canal itself, i didnt feel, but now 2 days later it hurts like hell..how can i stop it from becoming infected

The root canal procedure deadens the nerve and removes any infection in the canals by the use of meds applied during the procedure - so the pain is probably due to the nerve dying. Most rcs require more than one treatment and usually after the 2nd appt the tooth will feel much better. Have you tried taking an OTC pain releiver like advil or aleve?
