[|Human|] Hi goodday, my sister sumtime last week said she was getting blurred vision in her right eye, also she felt numbness in the right side of her face. She spent a night in the hospital under observation and she did CAT scans and blood tests and still they found nothing wrong. She was given some meds to take, and after a visit today, she said the doctor told her that she has Bilpulsey . I m not sure if its spelt correctly, but this is what she said. Can you shed some light on this situation please.
[|AI|]  Hello, I can understand your concern. We all have facial nerve on both sides of the face that has branches that run from temple, cheek, towards jaw and then to the neck. If this facial nerve s paralyzed due to some reason, then all the branches and the muscles they supply get affected and face loses sensations on that side. Usually, this nerve paralyzes when there is some lesion like tumor or trauma whicChatDoctorpresses or injures the nerve. However, if your sister had one of these reasons, it would have been diagnosed in the investigations at the hospital. Thus, she is either suffering from viral infection or idiopathic reason (the cause that is not yet determined). Symptoms of this palsy include loss of sensation and numb areas on the side of the face that is affected, Chat Doctor.
