General Curtis Lemay, the late commander of the Strategic Air Command, suffered from Bell's Palsy and it didn't prevent him from living a full and eventful life.
Wait a while, because the problem is often misdiagnosed.
There are theories about the causes of Bell's Palsy, and I have NEVER read or heard pregnancy being a cause.
Take the test to know for sure if you are pregnant or not. I have NEVER read or heard about this red line across the belly as a sign of pregnancy.
