Skeeter, I hope that this change will bring you lots of relief. You certainly deserve it. Did your Doc order a CT scan or MRI to find out what's going onin your back? She should have. After all, she's telling you she thinks you've ruptured a disc and that you may need surgery.
The reason I ask is because if the disc, or anything else is applying pressure to the spinal cord, it's IMPERATIVE to know that and correct it ASAP. If the pressure?injury goes untreated for too lon, it can cause permanent damage to the cord. My FIL had small metastatic tumors all along his spine and ended up literally stuck in the bed. He laid there for 4 days, over a long weekend calling only his Doc. The idiot (Doc, that is) never returned the call and no matter what we did, we couldn't convince him to let us get him to the hosp until he talked to his Doc. Welll, eventually we got him in and the Neurosurgeon said that if he had waited another 24-48 hours, the damage would have been permanent. Sure, he did have terminal cancer, but he was able to walk for the next 3 years -right up until he finally passed away. So please, push your Doc to address the cause of your increase in pain and lack of mobility. This is a real quality of life issue and you deserve answers and relief.
