hello and welcome to HCM,
First of all let me tell you that many of my patients have the swelling you mentioned without any problems whatsoever.
But any mass or swelling has to be properly examined by the ENT and only then we can be perfectly sure that you are fine.
So consult an ENT, ask for a proper examination and maybe request for a FNAC or biopsy
to confirm the diagnosis
take care and get well soon

ps: even scalp
lesions can cause the nodes to be enlarged like this which can be confirmed by the ENT
