Hi
Welcome to the MedHelp forum!
What you have is probably palpitations or awareness of heart beating. This can be felt as shakiness throughout the body or feeling of an impulse or vibration in the chest. Palpitations may be normally felt if you are overexerted. Chemicals like adrenaline, alcohol, caffeine, cocaine, amphetamines, and other drugs all cause palpitations. Disease (such as hyperthyroidism and pheochromocytoma) or mitral stenosis, panic disorder all cause this. Palpitations may be associated with heart problems, anemias 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.
I think you should discuss these possibilities with your doctor. It is difficult to comment beyond this without examining. A comprehensive investigation is required keeping all the points in mind. Take care!
