hi doctor, i have several lymph nodes( 27x8 mm largest one on the left jugulodigastrik node) that don t go away for 7 months. their size do not change significantly the lymp node that the largest one was 30x10 mm(but i think ultrasound has a little bit error rate) in terms of ultrasound they are bening but as i mention they don t go away I had an MR and Biopsy from nasal passage their results are good there is no solid mass in the neck area except several reactive lymph nodes i confused fully. i will have several medical process too. what i want to ask is that can dental infection lead this lymph nodes because i had an abscess near my molar tooth and 6-7 times my face swelled due to this abscess eventually i get rid of this teeth also i have perioral dermatitis for 3 years can this lead to lymph nodes ? and lastly, i have very big adenoid in the nasal can this lead to lymph nodes?
