What is the significance of nausea when pressure is applied to the suboccipital muscles? I have had headaches, necck pain and been sent to spine PT after a negative cat scan. I did have an abnormal MRI that was non specific, just noting 8 2-3 mm hyperintese foci on T2 and FLAIR. Also an area adjacent to the left Lateral ventricle was noted as questionable abnormal signal on the sagital view. I have been dizzy and notice vision changes if that helps
