Im not really sure what it is or what to do. evetything else seems to be fine, but i constantly get very abd stomach cramps (not at the time of my periouds) they also seem fine, sometimes i get very dissy and ive been itching random parts of my body (i.e. my sholdurs) please help. I also experienced a very bad headache and tired moment followed by a very minor nose beeld
