hi well come to Hcm.
Her bells palsy
has not any relation with Bells palsy.It is could be due to some viral infection of facial nerve
or some compression on facial nerve. Her BP is definately high
but not alarming and can be taken care of with simple oral medicine like amlodepin,atenolol
etc let it get settled in two to three days need not worry
and donot be aggresive on BP. Thanks
