Went doctors again yesterday complaining of chest pains. Refused ECG (3rd time). Done extensive tests on heart in January and all was perfect. Less chance than average of developing an arythmia. She listened to heart, took blood pressure and pulse and again said all was perfect. Woke up this morning trying to be positive and bang, my wrist, lower arm and neck is in pain (left side) why is this happening to me. I know I sit very tensed on my left side at work so it could easily be that but now I have 10'hours of work ahead of me whilst worrying about having a heart attack :/ 25yo male, this isn't life. I don't know what else to do. Having CBT that's not helping. Refused diazepam yesterday. What exactly am I paying my taxes and NI for??
