<s>[INST] Hello Doctor, This morning my husband woke with the sensation of not being able to control the right side of his face. It is not numb he has the same feeling on both sides. He can chew. He does not have a headache . However you can see a slight difference between the two sides. His right eye is very dry and he is finding it difficult to blink. He is 46yrs old with no previous health issues. He has never smoked. No obvious insect bites and no trauma. Any guidance you can offer would be very appreciated. [/INST] Hello Madam. Your husband has developed paralysis of right side of face that is why he is not able to blink and is having Chat Doctor.  Facial nerve controls muscles of our face and many diseases affecting it can cause such problems. You need to see a doctor (preferably neurologist) on an emergency basis who would see him and start appropriate treatment. The treatment response is generally good in such cases. Physiotherapy too would be needed along with medications. He should periodically close his eye using his hands. That would help in maintaining the eye moist. Artificial tear  </s>
