Some improvements today:
She was able to have an MRI this morning because she is now able to lie flat. The MRI was able to locate the source of the stroke which is at the brain stem. This is why her balance was affected and she hasn't been able to walk.
She was able to eat a little today without choking which is a very good thing. Yesterday she could not swallow.
She will be moved soon to a rehab facility where she'll be receiving therapy for a week or two.
Grateful for a few answers and improvements tonight! Thanks for your prayers; please continue to pray for her healing.
