Hi I've had pulsatile tinnitus in my left ear since late 2019. I had a brain scan late 2020 and all clear, hearing fine. They mentioned giving me a neck scan but they then signed me off after brain scan was OK. I've now asked to be re referred as I suffer from freezing coldness I.e my feet are always stone cold, hands, legs and arms are often very cold. If I go out for a 20 min walk even in the summer and them sit down in a cafe etc I start chilling down and my neck and ears are cold. Thyroid and iron levels all normal. I often hear the head beat pulsing in my head or neck as well as ear.
I have an appt at ENT on Monday, hearing ok but I'm looking for advice as thinking of asking for a neck scan this time to check carotid arteries and blood flow there. Does any1 have P.T and suffer from coldness. My heartbeat sometimes is low on rest atm it's OK and my bp is always normal or slightly low. I just want to insist on different tests this time. What else should I get checked. What causes others p.t?
Thanks
