Thanks so much for the feedback. Yeah, it scared me for sure. The numbness in my hands did not start until I was out of the studio and laying on my back with my feet elevated. A sports therapist who happened to be in the class said it was probably adrenalin, and my body kind of freaking.
I didnt hyperventilate in class but only after I walked out. I do overheat easily but I have never had anything like this happen. I really love that class and my teacher and I would hate to quit going, so I am hoping it was a one off deal.
I will get the blood test done. Thanks so much for the advice.
