Yes, it can get worse if the foramen gets MORE narrow and the nerves get MORE impinged. Then you can end up with permanent nerve damage, which isn't good at all!
So they're going to have to keep an eye on things so it doesn't get any narrower. Actually, they shouldn't let this go on too awfully long. Perhaps physical therapy could help. Talk to your doctor and see what he thinks. I'm just not sure.
