Re: Continued pain 5 months after microdisectomy
Sorry, but I am a bit confused. Is the MRI report you posted from a MRI that was done after your surgery in Sept? The report indicates the type of problems at L4-L5 that could cause the symptoms you describe.
An annular tear can be painful. Also you have a broad-based herniation that is pushing into the thecal sac. This is taking up space that is needed by the nerves so they can pass freely. In addition at this level the facet joints are showing signs of degenerative changes (wear and tear) and the ligament flavum is thickening, another sign of degeneration and something else that takes up space, crowding the nerves.
If this MRI is current, even though you had a decompression surgery on that same segment, it looks like there are things that would cause nerve pain still or again....
The dermatome for the L4 nerve runs down the front of the thigh, across the top of the knee and then down the medial side of the calf into the big toe. L5 runs more-or-less next to it, more on the outside of the calf and down to the three middle toes of the foot. A patient can have pain anywhere along the path of the nerve from the lower back to the toe.
