So, I had that appointment. Blood pressure was a bit high, but unlikely to be the culprit. The doctor suggested buying a blood pressure monitor and keeping an eye on that. I guess it's conceivable that it's all just anxiety/panic. I know that the last couple of days I've been feeling absolutely terrible, with episodes of rapid heartbeat and some dizziness as well. I started feeling better right after the appointment, so a big part of that must have been the anxiety. I did the mistake of reading medical stuff online. I know from experience that it's easy to psyche yourself into all kinds of symptoms.
Having said that, I'm not all that convinced that it's all in my head and neither was the doctor. I'll be having a blood test and an EKG taken next week. Diabetes and anemia were a couple of possibilities he mentioned. I had my blood sugar checked in November, I think, and back then it was something to keep an eye on, but nothing alarming.
You might think it was a good thing if it was just my nerves, but here's why it isn't. If it is just anxiety, then it's much harder to do something about it. So for that reason I was hoping for some concrete physical explanation. Then I could get medication and start feeling better.
In some ways, though, I am feeling better. After the appointment, I went for a walk - without the cane! I ended up walking much longer than I had intended. It felt really good to finally walk so carefree. I went to eat out and didn't feel deprived at all for not taking the pizza. I realize there's still a long way to go before I get to even where I used to be, but still, it's been a good start.
