Raindog,You might be able to consider this good news. Because this is a possible explaination on how you got your BFS. And if there is a problem, maybe there is a fix. So if you have some messed up lumbar disks, maybe if you work on core strengthening, or consider surgery, maybe there is a chance you will get better.I had an operation at l5-s1 and my twitching seemed to start about 1 year afterwards. I figure my nerves were healing and were not very happy.So now about 5 years later I continue to heal. I don't know the clinical reason for this. Maybe Kit knows. The neurologists and neurosurgeon told me that I would heal for a year or so and that would be it. But it is not the case because my continue to slowly have additional feeling on the left outer edge of my foot. And I do not get leg cramps as much as I used to.Now I take Tegretol and maybe that is some of it.Anyway, back to your case. First off lots of people have messed up backs, so that in itself I am not sure is a big deal. But if you got herniations pinching on your nerves, well maybe that is the cause of your twitching. And maybe if that is removed, you will get better.Anyway at least you have something to follow up on. Please keep us posted. I am interested in what the various doctors say to you.-43RichyThe43rd
