Abby: Bell’s palsy possible after having had chickenpox
Dear Dr. Roach: I am 55. I was having numbness on the left side of my face, and my left eyelid started to droop. I thought I was having a stroke.
I went to the hospital, and they told me this is Bell’s palsy. I asked where it came from and the doctor asked if I ever had chickenpox. I told him I had, and he said this is just another consequence, like shingles. No one in my house was aware of this.
Can I also get shingles along with this?
Now they say my face could clear up in a few weeks, or it could remain this way. It’s scary!
Dear M.N.: Bell’s palsy is a sudden (usually over a few hours) paralysis of the muscles of one side of the face. It is caused by damage to the facial nerve. The risk is greater in people with diabetes and in pregnant women. It often makes people worry that they’re having a stroke, because stroke can look very similar. For this reason, urgent evaluation is called for. A skilled examiner can tell the difference after a careful examination.
What they told you at the hospital is correct: One common cause of Bell’s palsy is a reactivation of varicella zoster, the virus in the herpes family that causes chickenpox. A different herpes virus, HSV-1, usually associated with cold sores, is the most common cause.
For this reason, antiviral medicines, such as acyclovir, often are given to people with severe Bell’s palsy, along with the standard treatment of a powerful anti-inflammatory steroid, such as prednisone.
Lyme disease also can cause facial nerve palsy, so treatment for Lyme must always be considered in a patient with apparent Bell’s palsy.
As far as your prognosis, it depends on how severe the palsy is at the beginning. If there is some movement of the facial muscles, a recovery is usually possible.
However, if the paralysis is complete, or if there has been no improvement in the first few months, then disability is likely to be permanent.
The facial nerve also is responsible for taste and for eye fluid, so abnormalities of these functions can be problematic, especially excess eye dryness.
