Symptoms:
irregular pulse (resting heart rate of 100-130.)
shortness of breath
severe and constant headaches (constant for 7 weeks, now i get them 2-3 times a week)
Slight abdominal pain at the top in between ribs when lightly pressed
Constipation
Nausea
Loss of appetite

I am 18 and have been experiencing these symptoms for 3-4 months. I am definately not pregnant.


I have had blood tests and a holter monitor, just waiting for the results. I have also had a head CT and that came back normal.

Does anybody know what could be wrong?
