The doctors say that Braxton hicks don't hurt but if you're not used to it or haven't gone trough labor before they can hurt a bit. For me since this is my third the Braxton hicks don't hurt they are just notable tightenings but I also have an irritable uterus so I also have uterine contractions that are uncomfortable and sometimes hurt a little often that are stronger then Braxton hicks ever are.
for me braxton hicks are mildly painful. with this pregnancy i've had a few already and i found them painful so far. if you are getting more than three an hour you should absolutely call your doctor or midwife.
i found having a warm bath helped ease my discomfort.
hope you're feeling better soon
You need to speak to your midwife they arnt painful just uncomfortable.
