(((sarah))), witnessing a stroke is scary and I know what you mean when you describe the way he talked too. I witnessed my mother have a stroke and we got her to the ER as quickly as possible. I was so scared and my older sister came storming through the doors and in front of everyone yelled at me and told me my mother's stroke was my fault.
I will say prayers that your son gets the care he needs and deserves and recovers so he can be healthy. Nothing wrong with asking questions and making sure he gets all the right care.
