Lower (right) Back pain!

Am I the ONLY ONE experiencing this right now? My lower right side of my back is super sore. Last night I went to L+D and they just said it was prelabour symptoms probably as I am not dilated at all (38weeks though). I was advised to take two extra strength Tylenol and a gravol and go to bed, which worked wonders for me last night. Tonight .. not so much. I'm dreading going to the hospital again because I know it's not labour and they will send me home.

Is anyone else experiencing this?
