I am so glad that you are back and alive.
I read through your story there several times.
Dammit Jim, I'm an architect not a sawbones...but:
I had two strokes about 1/2 hour apart in 2017.
I had quite a few of the same symptoms leading up to it, which I kept to myself.
Finally, I took a hard knock where my vision and sense of equilibrium went 90 degrees sideways while driving my car to pick up my wife. I recovered in a couple of minutes. When I got to her I told her what had happened. I had the second one in my driveway and fell across the hood of the car. Like yours, she called 911.
In recovery I learned a few things.
High blood pressure is a culprit.
Also sleep apnea. Something like 70 % of first time stroke victims have it, undiagnosted.
I now have a CPAP. That thing is a gift. I truly hate it, but I now sleep 8-9 hours a night with only one or two trips to the head. I have a lot more bounce in my step.
I take blood thinner, bp reducers, treatment for gout, a statin and some other meds but I feel much better.
I recommend you talk to a sleep specialist; it has really changed my health.
Oh and I did PT for a while until I got my balance back.
I'm very happy to see you back in the mix.
Bill
