Here's the input from Rambette, my lovely wife and a registered nurse:
First, the fact that he is already talking and moving is quite a good sign, especially given how far we've come in treatment for stroke.
Second, an ischemic stroke is far less serious than the hemorrhagic type, so it could have been much worse from the get go.
Also, it's likely that his shoulder pain was referred pain from the beginning of heart trouble. That doesn't matter now, but it's something that Freepers 40 and up should bear in mind if their left shoulder hurts persistently.
Question to any who might know, including Mrs Silverback:
Is an "ischemic stroke" different from a "TIA - Transitory Ischemic Attack"? Is it the same thing, only more severe, with more consequences?
I ask because my grandmother and my dog used to get those and the effects didn't last long, but they were considered strokes. Thanks for any info anyone has. Perhaps that will help.
