Last night I started feeling tightness and heaviness in my chest was not able to sleep unless I sat up straight. Today feel the same, except for the extra issues taking place right now. I feel like the left side of jaw area feel like it is tightening up, feel like I am out of it. I feel very nervous almost feel like I am sick to my stomach, but the nervousness beginning to feel very anxious, shaking in my right hand. Need some help. Left eye is twitching
