They are cervical lymphnodes
Normally,multiple lymphnodes are present in the neck.They get enlarged in many conditions like Infections,sarcoidosis
I prefer antibiotic like Cefuroxime
and anti inflammatory medicine initially to my patients with similar complaints.
If there is no response with in a week,i remove one swelling and send it for histopathological examination(Biopsy).
Please consult your doctor and proceed or you can follow my guidelines.
Wish you speedy recovery
