back pain?

I have been having a lot of back pain recently, and it is at the base of my back. It feels like my legs are made of jello, or if I move wrong I am going to fall over!
I realized that my stomach is really swollen, and I am not processing food again...has anyone else had this?
I don't have a bag, i was an immediate re-connect, so that is not an issue.
But I am just wondering if there is something else going on... Thanks!

Having read and responded to your other post...something is definitely wrong and needs attention.
