<s>[INST] Hi i have a 6cm large lump on right side of my neck under my ear and jawline but no pain or pus or problems in my mouth or teeth. The lump is hard i have tried antibiotics and diclofenac but it is still there. Could this be an abscess tooth or something else? [/INST] Hi, Dear,Good Morning. Thanks for the query to my Chat Doctor online-clinic. I studied your query in-depth.-In my opinion the lump in the neck under the ear-is mostly a Pleomorphic parotid Adenoid. Cause of the Lump-As it's not infected lump-as you thought-like abscess or else- and hence it has not responded to antibiotics.-Alerts-Its a slow growing Benign Tumor. You need not worry but initiate proper treatment URGENTLY.-Treatment -a-Consult A ER Surgeon who would treat it by partial-parotidectomy with Excision of the Parotid Adenoid.-Alerts/ Warning for couple consult your ER-Surgeon doctor and take treatment ASAP-is the Advice from me.-Hope this would resolve your worry-some query. Wellcome again to Chat Doctor. Have a good day. </s>
