Braxton hicks

I’ve had terrible terrible Braxton hicks starting yesterday morning (I’m 30 weeks) only in my lower belly at least every 2-3 minutes lasting hours and are pretty strong. Sometimes I have to stop what I’m doing and take deep breaths. I’m an avid water drinker so I know I’m not dehydrated. I had a regular prenatal appointment and mentioned it to my dr how painful they are and she sent me to labor and delivery to get hooked up to the monitor. The monitor showed little contractions but nothing they are worried about. Has anyone had painful Braxton hocks? How do you relive the pin or try and lessen them?
