Hi Alison,
I have problems with my blood sugars as well. Mine fluctuates up & down especially, when I'm on steroids! I don't feel well at all whether it's too low or too high. Yuck.
If it were me, I'd get to my Internist & have them check it out. It could be nothing but it's not something you want to ignore. If your doctor runs an A1C blood test (I think that's what it's called), it will give a 30 day average of your blood sugar.
From what I understand, low blood sugar can be one of the early signs of diabetes. Luckily, if caught early, a simple change in diet & lifestyle may be all you need.
I think a good Internist is essential when you have a chronic disease. You need somebody that sees the big picture. Neuro's are only interested in you for your brain.
Good luck & hope you feel better soon.
