Hi… my symptoms started with pulsatile tinnitus … I’ve had it 24/7 for about three years now. I had ct scan/ Mri and cerebral angiogram because they saw something on mri. Since then I’ve been told I have probable Ms . My neuro does not think my ear is related as it is constant. I have other symptoms too but pulsating ear ( and head sometimes ) with a loud heartbeat sound and extreme fatigue get me the most! There is a good support site for pulsatile tinnitus that may help called whooshers.com I have spoken to a few people now who had this type of tinnitus as their first Ms symptom. Keep us posted with how things progress, Amanda x
