did i have a panic attack or is it more serious? about 2 or 3 days ago I went numb from head to toe. my tounge had a tingling sensation like I had touched it to a 9 volt battery. and my heart was felt like it was going to jump out of my chest . The numb feeling lasted about 5secs. the racing heart lasted a few mins. It happened again last night but this time I wasn t numb. Just a racing heart and light headedness. I went to the emergency room and was given an ativan prescription. Can anyone give me an opinion. I am 23yr old. slightly over weight. and otherwise healthy. Thank you for any and all help. I appriciate it.
