Hi Michelle,
Here are a few things to try...I'm a Registered Massage Therapist, so slightly biased HAHA! But a massage would help you if it isn't contraindicated. Usually we suggest a massage before going to the chiropractor. This will make the chiro adjustment last longer because the muscles are loose and not guarding.
Also try epsom salt baths 1/2 cup to every 50 lbs of body weight.
Ice is also great for taking down any swelling to the area especially after a treatment. You could also try "flushing the area" heat for 3 min. then cold for 30 sec do this 3 times ...always end on cold.
One more thing ...take 2 tennis balls , put them in a sock, tie the open end . Lay on the floor and place the balls where it hurts on either side on your spine. try to lay there until the pain eases off.
Oh, if you do go for massage... try to find a clinic that has a pregnancy pillow so you can lay on your tummy!! good luck!!
