A bit of background - I have been suffering from anxiety for around 4 years now. Early last year I managed to get a lot of my symptoms under control and I went most of the year with relatively low anxiety/pain. However, around October, I started getting sharp and aching pains in my arms, hands, neck, and sometimes legs. The pains were mainly on my left side, however this subsided within a few months.
As of yesterday, these pains have come back, however they are a lot worse and a lot scarier than before. Yesterday I woke up and every time I got up/walked/excerted myself at all, my I would get this shooting pain from my left chest going into my armpit and up the side of my neck. I went to my GP and had an ECG and chest x ray done, which came back fine. Today I woke up and my entire left arm is in pain, constantly. The pain is a dull ache with frequent stabbing pains near the armpit, elbow, and wrist. I'm also having oxassuonal stabbing pains in my neck and right elbow.
I'm absolutely terrified this is my heart - although I've had ecg and an x ray which have come back fine, But i know that they can't show blocked arteries or other heart conditions. I'm supposed to be going on holiday tomorrow morning but I'm terrified and on the verge of cancelling - I've no idea what to do!
