I had a mental breakdown 2 days ago and hurt myself by squeezing my throat so that my arteries in my neck were blocked off for 30 - 60 second periods at a time. I had petechiae, which is expected. But I've been feeling very weak and had an unrelenting headache at the back part of my head and my forehead. I'm not a danger to myself. I want to make sure I haven't caused serious damage. Should it be looked into or just waited out?
