@Yvonne-1 - You cerrtainly have gone through the mill of late, but the good news (if there can be any, having met unexpectedly with the pavement) is that this is a known situation now with yourr GP, and he seems to have taken note, and ben keen to garner follow up opinions.
My advice to you would be to try not to jump to any conclusions about what might or might not be going on - especially so soon after a shocking experience such as you recently had.
Nobody he can advise you what you are suffering from, or indeed if any given symptom is a cause for concern, or "just one of those things".
As others have suggested, it would make sense to think a bit about all the things you want to know when you see the Doc, and to write them down. Then, when you see him, you can check at the end of the appointment that he/she has covered all the aspects where
you have concerns. Let's face it; it's your appointment, so getting what you need and want from it is important.
Also in the meantime, it could be helpful to keep quite a detailed diary of your blood sugars, if you test, but certainly of how you are feeling, and what, if any, symptoms you feel you have on any given day, because on the spot, in an appointment, it's not always easy to remember if you have ever felt x, y or z. You may even be able to see some trends in what happens when that could help identify root causes or potential treatment/workarounds.
If in the meantime you are feeling unsafe in any way, going about your day-to-day activities, please go back to your GP and ask to be referred to an Occupational Thererapist. I've not had to use an OT in the past myself, but I know when my Mum was having some mobility issues the person who gave herr back the most indepence and confidence, in the shortest time, was the Occupational Thererapist who just knew some greeat "stuff" about managing symptoms to stay safe and functional. Of course, it is still very important to get to the root cause of what's happening.
Take care Yvonne.
