Warm baths and massages. I take on average about 3-5 baths a day because of the pain I have this pregnancy.
Ok I'll try that using bubble bath n bubble salt ok
Try some yoga positions to take the pressure off the tailbone. Also laying on the floor with a firm pillow supporting your lower back and tailbone while I stretched or read for an hour helped for me. Also time in the pool takes pressure off joints.
I had this problem during my first two preg... dr said it was my siatic(sp?) Nerve being pinched and unfortunately there isn't solid hog can dip other than warm bath and massage the area.. is from you hips moving getting ready for birth..
