In the last few weeks i have been feeling like there is a lump in my throat and when i lay down with my son for a nap, i feel like im choking. I also have a funny feeling coming up into my throat, like air bubbles. I get chest palpatations with this as well, it's very scary. I had broken my ribs a few months ago, and i thought perhaps this was related. My doctor says not. I do have problems with anxiety and stress, could this be related to stress, or do i need to fear of something major. I don't smoke never have, but heart conditions run in my family. My father died of congested heart failure, and i do have mitral valve prolapse. Please, if anyone could give me some advice for this, i would appreciate it, I feel like i'm hitting a puzzle that i can't figure out to solve.
