Thanks for your query, I have gone through your query. The swelling could be because of the gum infection around the root canal treated tooth or tooth infection from neighbor tooth, or it can be incomplete root canal treatment. Consult an oral physician and take radiograph to rule out these things. You have to take metronidazole along with penicillin. Do not apply hot or cold or pressure over the swelling it will become more. Consult a dentist and get it treated. I hope my answer will help you take care.
