I m a 43 year old woman, 5 7 , 217 lbs. For the last few months, I ve had on and off shortness of breath, racing or palpitating heart, fatique and periodic indigestion. I m overweight, so assuming something to do with that... However, for the last couple weeks, It s been getting worse and now when I feel the heart palpitations, it s like something pressuring my throat or something - makes me almost want to cough? I also have tingling in the backs of my legs.
