I sympathize with you for your GP’s resistance to your description of pain throughout. I have just been through similar from my last appointment to discuss my long term cervical pain and the returning lumbar pain as well. I was so disappointed by his dismissive attitude towards what I was trying to tell him, I’ve made an appointment with another NS at a hospital close by.

I have to say this is very frustrating as he did my last fusion in 2023, which felt so successful then.
He ordered a spect nuclear bone scan of my cervical area, and a full MRI of my neck and lumbar areas in May.
He asked me my symptoms at my appointment in June, when I said the worst was a shocking pain lasting only seconds that blasts up my left side of the neck and down, into my shoulder, and my pain is mostly on my left side down my leg, into my foot and toes. My last MRI ‘s show a number of problems such as bone spurs, bulging discs, mild to moderate stenosis, flattening of cord around c5-6, c7, even some activity at left side c2-3.

His response was this does not match your MRI, the damage is to the right side. The shock does not come from your neck, and that was essentially the end of his listening. I never got to the rest, really, other than my pain wrapping around my neck giving me headaches. Pain when turning my head up and down like when I’m in church trying to follow along, shock-like pain.
When I did a search right here on our Mayo forum, I found something called Lhermitte’s sign? Is that correct, which describes my pain exactly!
I feel so upset when a highly skilled doctor just doesn’t listen, his views are narrow and perhaps he thinks I’m an old lady who just has arthritis.
I won’t give up, I’m determined to find answers to my neck pain.
