Hi! I just had an experience where my heart started beating very fast, my vision went white and I couldn t see anything, I got very dizzy, my face, tongue, and neck went numb, and there was a pain in my chest. It s been about 25-30 minutes since that happened and I still haven t regained feeling in my nose and my throat is straining on my left side. Occasionally i will get a small pain in my chest on my left side as well. I feel as though I am floating and lights are very bright.
