Interesting just 10 days prior to this happening I had a minor procedure under general anaesthetic. I watched as the attendant fiddled around trying to get the IV into the back of my hand the whole time with no effect whatsoever.It's kinda random sometimes. I am NEVER bothered by IVs, needles etc but when I got a colonoscopy recently I got super dizzy and nauseated when they put the IV in. Could have been due to all the prep, fasting etc they said. Hopefully nothing serious, maybe they could consider adjusting your dose if you see this more. It's nice you have your echo soon.
