a couple of months ago i went to my gp andvsaid i had a lump in my neck and i had an ear ache. he gave me anti biotics for seven days. i then started to have chest pains and shoulder pains and my neck was inflammed. i went to the walk in emergency and he sent me to ent ward . as the lump was on the main artery. my blood pressure was up and my ecg was irregular. he gave me another course of anti biotic which took the swelling down but the lump had got bigger. i went to ent today and they stated it was not a lymph node and could not do a biopsy because of it being on the artery. i am waiting for a ct scan and seeing the radioologist

Hi, Thanks for query to My Chat Doctor virtual Clinic And welcome to Chat Doctor services. I studied all details of your query. I understood your health concerns about remedy of a lump on artery in the neck. Based on facts of your query, it seems that-you have a lump of infective origin with your earache. Due to its weird progress, many causes need to be worked up. ENT Surgeon has already asked a CT Scan. Second course with changed antibiotic controlled its swelling, but the lump got bigger. In such a scenario I Would suggest Second Opinion from another ENT Surgeon in the meanwhile. In my opinion-this could be Bronchial Cleft lump of first/or atypical second bronchial cleft/ or could be hidden Cystic Aroma with Infection. The association of the earache, increases its possibility of being First Bronchial Cleft which extends to external auditory canal. But its relation with the carotid artery needs to be confirmed as, in that case Second Bronchial Cyst possibility increases. These are congenital anomalies due to embryological defects in the closure of the clefts. Remedy-Conservative approach is preferred due to the proximity with carotid bifurcation. Surgery does not guarantee recurrence and hence Conservation is to be preferred. Hope this reply would help you in resolving this complex query and anxiety with it. I would appreciate if you hit thanks and write excellent review comments to help needy visiting patients at Chat Doctor. Welcome for any further query in this regard. Good Day!! Chat Doctor. N.M.S.
