Hi Gretchen! I've fallen more than once. Luckily, most my falls have been close to home. For a long time, every time I turned a left corner, I would fall. It was really weird and yet funny. That has since gone away and I started using my cane which helped. I have had more close calls than actually falling. These close calls happen all the time but I have always been able to grab on to something to break the fall. My last out of the home event was last week. I went to PT and when I got out of the car my right leg wouldn't cooperate and got caught on the door jamb of the car. I caught myself and didn't fall but definitely looked around to see if anyone noticed.
Is it possible you are having an exacerbation? Maybe a call to your neuro would be a good idea since you are still having some trouble.
And, btw, TBI is traumatic brain injury.
