I don't normally post on this board but do read it once in a while. I can't believe others share this symptom ... I thought I was the only one. Two years ago I had daily chest pain/tightness and was sure I was having or going to have a heart attack. The dr. ordered an EKG and a treadmill stress test ... both came back fine.
Last October the chest pain/tightness returned and with it the 24 hour anxiety that this was something more serious. I had a second treadmill stress test which came back fine again and was told it was anxiety. I have had anxiety for 20+ years and this is a symptom I didn't have before.
In answer to your questions ... I get this, it has occured daily, it was there 24 hours on some days (I would wake in the middle of the night to chest pain/tightness) and I didn't find relief ... it just eventually went away.
I researched it to death and found this;
Other causes of chest pain include:
Strained chest muscle from overuse or excessive coughing
Short-term, sudden anxiety with rapid breathing
Peptic ulcer disease Pain from the digestive tract, such as esophageal reflux, peptic ulcer pain or gallbladder pain that may feel similiar to heart attack symptom
Hope this helps
