I'm a veterinarian trained in animal acupuncture. The question is for myself. I have a trigger point in my neck, roughly at GB21. If I hold my head a certain way, my hand will tingle then go numb. If I attack the knot with acupuncture needles, the tingling happens instantly. Radiographs show no bony lesion in my neck. I am scheduled for an mri next week. Anyone know whether an mri will show lesions in the area of the trigger point? The doctor is expecting to find a nerve root being pinched by a bulging disc. Could this lead to the trigger point that I'm dealing with?
