I'm sorry that you now have evidence that your MS is clearly progressing. We all know that MS continues to wreak havoc with the myelin -- forming lesions -- even without external signs, but in your situation, you've got the external problems to support the progression evident on the MRI.
I'm sorry you're having liver enzyme problems. Have you considered Copaxone? It's not an interferon, so the liver issue shouldn't be as great.
I can't (and won't -- I'm not a doctor, nor medical professional!) specifically interpret your MRI, except to say it's pretty clear even to a layperson like me that your MS is progressing, new lesions are occuring in all sorts of places, and your body is being affected in lots of ways. I hope your doctor will spend sufficient time with you to answer your questions fully and completely, and find a treatment that will be helpful for you.
