Does your pain follow a specific Dermatome?

My MRI that I had a year back showed a medium herniation at L4-L5.

I have noticed that my sciatic symptoms follow several different dermatomes on a chart. the front and back of my calf will hurt, or the top and bottom of my foot will tingle, though not at the same time. It seem to follow both L5 and SI pain maps...

Does anyone else here experience this? I know nerve root compression is supposed to follow a specific pattern down your leg.


  • MRI's are not the 'tell all' for what is going on (or not) in your spine. You can have a nasty MRI and no symptoms, or nothing really showing and all sorts of issues.

    Remember, osteophytes (bone spurs), alignment, disk material, narrowing (stenosis) etc., all can cause issues. The key is not all is evident on an MRI. Compressions (crushes) can also occur away from the spine. Dermatomes on these maps are general, in that the lines can and do overlap on some. They are just a basic guide for us to use.

    What you might want to do is keep a journal as to what is going on, bring that to your doctor and see where to go from there. I hope you have answers soon. :)
