Hello all, I'm having pulsatile tinnitus for the past two years. I have taken MRI scan which came out clear, second opinion from a neurosurgeon suggested that I may have venous sinus stenosis and told me to take MRV scan. In addition to these, I have Vitamin D deficiency and high cholesterol (on statin). With all these condition, is it safe to take covishield vaccine? I know it might sound silly, but having read the blood clots issues of AstraZeneca covishield, it makes me a little scary for vaccine since I may have stenosis.
