I get shooting pains in heart. Get like 3 to 4 shooting pains in heart. They are very painful, they stop me what I´m doing. I gotten all the test, the 24 hour holster and the Electro and the Stress and the bloos pressure test all of them and all are ok. What could this be. I get them and they pass and then I feel kinda weird without any strength and then after a while I feel ok. Could this be stress or something else cause all my tests are ok.
