Had blood test that showed poss. diabetes few months ago. Moved to another state due to family crisis. Have dr. appt. set up, but not for a few weeks yet. Two days ago, got weak and woozy in grocery store. Couldn't stand up. They said I was incoherent for a few minutes. Gave me orange juice and a lady gave me a glucose tablet. They called family to pick me up. Spent rest of day in bed, was absolutely freezing. Severe abdominal pains as well. Now, two days later, still weak and a little shaky. Could it manifest this way and do I need an emergency room visit?
