Ive been to the emergency room two weeks ago because my heart started to beat irregular and felt as I was losing air, like I couldn t breathe. I was tested for thryoid problems along with lung x-rays and blood work and everything came up good. No cholesterol or high blood pressure.even though the doctor said everything look good, he reffered me to a cardiologist but haven t gone do to I don t have insurance. I ve had this problem for about three months now, since then Everytime this attack happens I ve notice I have to use the bathroom and after using the bathroom I get this feeling Everytime I breathe I begin to feel fatigued and feel like I can t breathe as well. I recently found out I had a pea size external hemmorid don t know if this might be the cause to all this problems or I ve been having severe allgeries to dust at work and can t stop sneezing.
