How serious can a lump in the next be? My mom has had a lump in the right side of her next (about where a lymph node would be) that has been swollen for nearly 2 weeks after receiving a root canal . She was put on antibiotics and none of them seemed to work. The lump has become larger, harder, and she has begun to feel more ill. Fatigue , exhaustion, overall sick. Blood work was taken over a week ago and we still haven t heard back and are unable to get in touch with the doctor. Is this something that can wait until we finally hear from the doctor, or should we head to the emergency room?
Hi, Thank you for the query. Lump in the area of the teeth where RCT was performed suggests of any periapical cyst formation, because of infection it may lead to lymphadenopathy, which will present with fatigue, fever, pain, and swelling. Just taking antibiotics will not help you. See your dentist, get an x-ray done of the area affected and rule out the exact cause for the formation of lump. It has to be treated according to the diagnosis, if it is a cyst then a surgical excision is required, if lymph node enlargement due to re infection of the RCT then RCT has to be repeated. Hope this information helps you. Take care.
