Hypoglycemia?

Ka

If you have hypoglycemia as a child, do you always have it? I had issues when I was around 2 or 3 years old. All these years(I'm 25 now) I haven't been bothered by it. Today after lunch I started to experience extreme nausea, a lightheaded/dizzy/weak feeling, headache, my vision got blurry, I couldn't stand up straght, and found breathing to be a little difficult. When I got home I checked my sugar using my dad's glucose meter and it was 94. This was about 5 hours after eating lunch and no snacks in between. Anybody that can tell me if this sounds like hypoglycemia or something else maybe?
