It turns out I have a herniated disc between my C5 and C6 vertebrae (that's in the neck). The doctor recommended (of course) that I stop aikido, then in response to my look recommended I not fall on my head or neck.
Herniated discs never get better and can't be fixed except with surgery, but that's only for very extreme cases.
I am wondering if there anyone here who is training with a herniated disc in their neck. How is it going? Do you modify your practice? Do you take risks? Do you ever worry about it?
I note
this post from Kevin Leavitt, but that is all I found by searching the archives of this forum.
My symptoms started after an incorrect nikajo (nikyo) osae, but may be related to trying hiyaku ukemi with a poorly performed kotegaeshi or have no relation to aikido. I have a pins and needles sensation from my right shoulder down into my right thumb, which has lost a lot of sensation. It is pretty much constant, but sometimes gets better or worse. My MRI looks pretty much like this:

I will try to alleviate the symptoms with vitamin B12 but that is all.
