Hello docs! I had smoked weed (marijuana) and it wasn't my first time but dunno what happened that day suddenly I got so scared due to too high and I couldn't control. Since next morning I started feeling afraid and scary and my heart beat pounding too fast and I feel my hands and legs would shake. My mind is full of scary feelings and my left top side of chest start paining. I had gone for cardio and everything came clear. I feel pathetic about my condition and just wanna cry out loud. The pain is also not going. It reminds of that event again & again and I feel pity. The cardio doc had prescribed beta-blocker for a month but still I have pain in the top left side of chest and scary feelings.
