Lump between jaw and neck. One post!

Hi I have already made one post regarding this about small lump between jaw and neck and no issues ur pain in that area or fever for past 6 months As  per advice from portal I went to ent specialist in Delhi to get my lump checked he didn't even check my history or directed any test He simply wrote one antibiotic and one probiotic and told to eat it for 5 days and if lump is completely gone don't take follow up otherwise we will start with some test As told I don't have any fever ,pain or any throat issue so atleast he should have done complete followup he simply touched the lump and didn't ask I informed him that I had no symptoms or an fever he instead asked  that why I waited for months to get it checked didn't give any clear answer what it could be or what steps should I take instead gave an antibiotic and probiotic treatment Should I take a second consult as I don't feel he is doing right diagnosis Meds given capsule cyraflora and tablet moxikind cv 625 for five days
