My only experience of tingling is as a precursor to a visual migraine. Starts in the ends of my fingers and works its way up. Then later my vision will go askew, sometimes followed with nausia and dizziness. Migraine relief and sleep are the only things that get rid of those for me. Those bad boys can be triggered by anxiety as well.
Anyway - best bet is to get checked over by the doc again.
Hope you're feeling better now anyway.
