@ablack2008,
At this point everyone is trying to help by giving possible reasons for her symptoms and they are worth considering. But you are correct in seeking a complete evaluation. The spell she just had could be anything from heart, neuro, sugar levels. It is impossible to tell. Nothing in body works independent, when one thing is not working, it can lead to other problems and symptoms. It is identifying the primary or co-conditions that is difficult. That is why she needs a clinic that does a comprehensive evaluation.

Mayo and Cleveland Clinic are both excellent options.

Have her providers been willing to do referrals, or are you doing self-referral?
