ENT consultant visit today...he actually listened. Reckons I've got menieres symptoms rather than vestibular migraine. Going back on the betahistine- low dose 8mg for ear pressure - and going to persevere. It was good being listened to and was given a 6 month open appointment to return if further problems. This makes up for the dreadful first one...3rd time lucky! He explained overlapping symptoms, problems treating menieres as older treatments now discredited etc.
I had a vertigo attack on the way and stumbled in the hospital car park, which may have been stress related. He advised rest, healthy eating, cut caffeine, salt (recommends not to cut salt completely as zero salt can cause depression, didn't know that) ...I feel like I have a plan! Hope you are all managing ok. xx
