So I keep blacking out for minor injuries. At first i thought it’s because of dehydration but then whenever any minor injury happens I keep blacking out. This one time I blacked out because I was walking in the sun for sometime. Next I blacked out literally because of constipation. Then I blacked out because of my period cramps . I again blacked out because I slipped and had a hard fall. Finally I fainted because I bumped into something. And all this situation nothing major actually happened . Should I be worried ???
