<s>[INST] Hello Ive had issues with my blood pressure recently 170/120 I noticed some swelling in the bone behind my right ear its tender to touch and I still have three other bean sized swellings behind my neck I have a constant head and insomnia wont stop. Ive completed my prescription of lexotan for 3days but I still cant sleep. Im worried the lumps could be affecting my brain or something [/INST] Hello, I have gone through your query and understand your concern. I suspect it be a Mastitis in Right side. That bean shaped swellings are the enlarged lymph nodes in neck due to Mastitis. It is nothing but an infection and inflammation in the air cells of mastoid bone. It usually spread from middle ear infection. Lexoton does not cause this mastoiditis. It is a Chat Doctor. You need further blood investigations, X-ray mastoid. After these investigations, you may need antibiotics and painkillers like Ibuprofen. As you suspected, it may spread to brain and meninges can result in meningitis and brain abscess if left untreated. Thus consult a ENT Physician and investigate and get treated. Once you get treated, these swellings behind the ear and neck will subside. As your blood pressure is too high, you should take Blood pressure medicines continuously and check your blood pressure regularly. Hope this helps. Please write back for further queries. Wishing you good health. </s>
