Hi, I am a 24 year old female and have been having fainting spells for the past 4 years, which i noticed started happening after I had a miscarriage . I get them more frequent now. I have been to the doctor and they just say anxiety attacks . I really dont think thats it . I have made them do blood test, heart test,liver and gallbladder test, all came back fine. These episodes make me vomit and feel as if i have to make a bowel movement, I also turn pale and lose vision and hearing. I ve been experiencing headaches everyday also. I just want to find out what it is.
