Hi, and thanks for your medical question on eHealth forum!
Palpitations may be associated with heart problems, anemia, low blood sugar and low blood pressure. If you have cough and are taking medicines that contain asthalin or terbutaline then the palpitations can be a side effect of the drugs. Disease (such as hyperthyroidism and pheochromocytoma) or mitral stenosis, panic disorder all cause this.
Chest pain radiating to arm and neck is usually due to angina and peiricarditis. If EKG is not catching anything, then maybe you should opt for a holterâconsult a cardiologist. Also acidity, gastric reflux, IBS, spleen issues should be ruled out. Costochondritis is another possibility.
Since a confirmed diagnosis cannot be given on net please consult your PCP regarding this. Hope this helps. Take care!
