I'm pregnant and due next week. My back has been hurting, is it okay if I use a heating pad?

Yes. When pregnant you do not want your entire body heated to a high temperature, so avoid hot tubs & saunas, but it is perfectly safe to apply heat locally. Some people say heating pads generate an electromagnetic field field with potential harmful effects if used long-term, but it is safe now & then.Another alternative is a hot water bottle.Massage might also be helpful. Good luck with your delivery!
