anxiety causing chest pressure ?

Hello,

Im 22 years old and I have been feeling under the weather for about 7 weeks now ever since a night of badminton. Around 50 minutes into it I became very aware of my own heart beat and had to take a rest for 5 minutes because I felt light headed and I felt my heart race. After 5 minutes i resumed plaing and things seemed to have subsided. However, ever since that night I have had a constant slight pressure in my chest and have a range of symptoms that i gone with this.

At various points of the day, everyday, I get an overwhelming sense of unease that starts with the chest and manifests itself as a fuzzy head or a throbbing sensation just above the jaw. I usually get a flush feeling as well and gets particularly worse when im with a group of people.

I have had an ECG and an Ekko and both have come back normal (well my Ecg 'fell within normal range'). I have also had a blood test and this has also come back normal. I am now fairly convinced that it is not a cardiac problem, although i am going back for a stress test and then to wear a cardiac tape to measure the rhythm over a day. I am also fairly sure that anxiety makes these symptoms a lot worse which has explained why I feel worse in big groups (eg. cinema, at gigs and at restaurants), however when i am most relaxed the symptoms still come on.

For example when i get home and watch tv, I stil get the feeling of unease and headaches. It has also come on when I have been playing golf and shopping as well as at other seemingly relaxed times.

I was just wondering whether this is all down to anxiety, or whether there are other non cardiac related sympotms that can bring on this type of illness before its made worse with anxiety. Also, soemthing must have happened the night I played badminton, even though all my heart results seem to have come back normal. Either way these symptoms are really getting me down and my confidence is being shot.

Any help would be great.

Many Thanks
