Several times a day I get a numbness and tingling sensation in the heart area... I kind of bump my heart area with my hand and the sensation goes away. This can happen several times a day or not happen at all during the day. I do have borderline high blood pressure. I don't drink or smoke. I take Claritin D daily for allergies. I am normally healthy although I am a bit over weight 275 pounds.. Any ideas on what to look for or what to be aware of?
