My mother was, a few weeks ago, diagnosed with a broken-off disc in her cervical vertebrae. The technical diagnosis is "anterior cervical discectomy and fusion", in her C-5-6. She had been having very intense pain in her left arm for a few weeks before the doctors did an MRI and found out that this was the cause. Upon seeing how bad her condition was, a neurosurgeon fit her into his busy schedule within two weeks after the diagnosis. My mom, who hates all these related to doctors/medicine/procedures/etc, asked if there were alternative options--physical therapy, or simply waiting it out. The doctor told her that physical therapy would actually make it worse in her case, and that it could take anywhere from 6 weeks-1 year to heal (I think I remember that correctly). He also told her that, in the meantime, any sudden jerk or fall could cause her to be paralyzed, if the disc were to touch her spinal cord.
Almost immediately after getting told she would have to have surgery, my mom claimed she was feeling better. She said that she had no more pain in her arm. However, about two days ago, her legs from the knee down started to tingle and were weak. She went to the doctor for this, wondering if it was from her disc, and he said it was simply nerves. When she told him that she had no more pain, he told her that she wouldn't need the surgery after all, without even running any tests or taking another MRI. Granted, he might not be able to see a change in her yet, but I still think that was something that should have been done. He tested her arm's strength and said that it had improved.
I guess my question is this--have you ever experienced anyone with a broken cervical disc heal so quickly? Is it possible that she has convinced herself that she's feeling better to the point where her mind actually believes it to be true, and her body follows? I'm really worried about her. She thinks it's a miracle, but I'm not so sure.
