Lifting my eyebrows does not really work symmetrically. The left eye did not blink, the right one did. To my astonishment this wasn't possible. The air escaped through the left side of my lips. I was diagnosed having Bell's palsy.
Recovery is mostly a matter of time.
I am prescribed eye-drops and an eye patch in order to prevent my eye sustaining damage due to dehydration or abrasion. Little appears to be known about how to cure Bell's palsy. Now that I know what the problem is, the question which remains to be answered is what caused it. For a second opinion I made an appointment with a neurologist next week. Because this won't take place until Thursday, my doctor insists on seeing me back on Friday.
