It's my pleasure. It must be a real weird and scary change that you've been hit. You're going to see a doctor, but I would also recommend seeing an SLP (Speech-Language Pathologist) as they would be able to tell you more about the stuttering, assuming thats whats really going on. When you stutter though, does it feel like a *block* in your throat where you just cant get the word out? like your vocal cords in your throat close and the air gets locked?
