Hello and thank you for using HCM. I carefully read your question and I understand your concern. I will give you my opinion and explain you something. You should know that heart pains have some characteristics. Usually they are retro-sternal pains like squeezing, tightness, heaviness.They may irradiate to arms,shoulders, jaws, last from 5 to 20 minutes. They might be associated with fast heart beats, nausea. A prickly sensation, lasting day and night its not a typical heart pain. If it was a heart pain, something should has happen till now. It seems much like a muscular, scheletic or neurotic pain. My opinion is that this is not serious, you should not worry. You don t mention your age, but if this really bothers you a lot you should go to the emergency and they could check this. Or, if this continue you can make a full check up. I will recommend a electrocardiogram, the cardiac enzymes, a cardiac echo and after this a stress test to exclude heart problems. Hope I was heplful. Best regards.
