I wake up with the feeling of something like a screen on a screen door pressing really hard directly under my throat in the middle of my chest and it feels like a big square area , covering from the very bottom of my throat to the top of my breast area , seems about 6 to 7 inches across and down .. pain is severe and then passes after about 3 minutes though I feel worn out after .. just started about 3 weeks ago , I m afraid to go to sleep ? It happened 3 times last night , also when I woke all the way up in the morning , my left hand and some of my arm was tingly and numb feeling , that lasted about 5/6 hours Thank you kindly for any helpful answers
