I am hoping someone can tell me what all this means as I did not ask. I was referred to ENTdue to longstanding pulsitile tinitus which I can usually stop by moving my neck. I had sinus surgery not long ago (via community GP specialist referral) and mentioned it to the surgeon who suggested this referral. I had some balance tests starting the Hallpike test which made me feel extremel unwell (just as well I had not had breakfast) but did not show the eye movements they were looking for. (I had nystagmus whilst suffering from labyrinthitis some years back). I then had to stand and march on the spot but with my eyes closed and when I opened them I was facing the wrong way and in a slightly different part of the room. Then I had to walk heel to toe along a line which I struggled with but absolutley could not do it with my eyes closed (I had to be caught a few times). BP measurement showed orthostatic intolerance ( I kind of knew that as I get very tachicardic when standing still and have always had difficultie standing too quickly). I have been discharged but will have an MRI soon and am still waiting on cardiology. Do these test results mean anything or is this all normal (for someone with OI). Thanks
