Hello, I have gone through your query and understand your concern. I suspect it be a Mastoiditis in Right side. That bean shaped swellings are the enlarged lymph nodes in neck due to Mastoiditis. It is nothing but a infection and inflammation in the air cells of mastoid bone. It usually spread from middle ear infection. Lexoton does not cause these mastoiditis. It is a drug for insomnia and anxiety. 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.
