Hi my name is Lyn, I am 39 yrs old, I am average height and am very overweight (140 ish kg). I take medication for insulin resistence and irregular heart rhythm. I have had indigestion, slight shortness of breath and the feeling of something stuck in my throat for about 5 days now. It came on suddenly and increases and decreases with no routine . I recently had my blood pressure checked and that was fine but my resting pulse rate was 100. What could possibly be wrong ??
