Hello Rchelle5,   I had the same thing happen to me.  One night I went to get up out of bed and I felt something pop in the very lowest spot on my spine.  Ever since then I have the same problems that you are describing.  I had an MRI and unfortunatley had popped the disc between L5 & S1.  The pain is horrible right now.  Nothing seems to help.  I'm on Morphine and Norco for the pain and Gabapenten for the nerve pain.  I am seeing a Neurologist/Surgeon in 3 weeks and will probably end up with surgery.   Standing to do the dishes or anything is impossble.  Right now it hurts to sit down or lay down.  I can only lay on the opposite side with 2 pillows between my knees to sleep.  You should definately get it checked out, especially if you are wanting to get pregnant.  Good Luck!!
