    i have posted here before, I recently have reherniated my l5s1 for the 3rd time and my doctors are recommending a fusion.

    In recent days I have begun to feel numbness in my upper back (last 2 or 3 days). It is more noticeable on my left side (which is the side I herniated my l5s1 and also the side i had a previous cervical herniation).

    I was wondering if the upper back numbness could be related to the l5s1 herniation and/or is it possiblt a sign of a more serious issue? I have not found any literature on any connection and I plan to discuss the numbness with my doctors, but it seems hard to think it is unrelated since it has followed my most recent herniation.

    if you could point me to any literature or tell me what I should be looking for in the literature that would be great.

    The doctors are correct in recommending a fusion after your third herniation.

    Upper back numbness is not related anatomically to the herniation at L5-S1. I have seen many patients develop symptoms after the onset of the initial symptoms that are unrelated but seem to go away with elimination of the original pain generator. This may be to the crossover phenomenon. Nerve signals cross over in the cord to the opposite side and it has been speculated that this crossover can produce “cross talk”.
