I have nighttime panic attacks sometimes.I didn't even realize I was that stressed until I started having them.I have always had anxiety to varying degrees throughout several years.I started having chest,arm,shoulder,pain.I would get hot flashes,waves of heat/numb sensation.I would tingle.I couldn't stop thinking about death all the time.I was always thinking I was having a heart attack.Trouble breathing,lightheaded.I hope this helps.I went to dr. and had EKG,chest xray,labs.He said anxiety.I started taking sleeping pills(lunesta).Once I convinced myself it was anxiety,I was able to control the attacks a little better,or maybe my brain.He also gave me Xanax.I stopped taking both.I am going to go get some Prozac on Friday because my daytime anxiety is not good.Good luck to you and keep us posted.
