I bruise really easily and a month or so ago I got really bad bruises on my hip from hula-hooping. After a couple hours I actually started to feel sick, like my stomach hurt and I just felt bad. The next day I felt ok and the bruise finally went away after a week or 2. I went and got a pedicure today and got a bruise right on my spine from those massaging chairs. I felt ok until a little while ago I start to feel sick. Do the bruises have anything to do with me feeling sick...is it normal for bruises to make you feel weird?
