I'm trying to find out what this one is..
It's injected into the bloodstream via typical sized needle, it's clear, and everything gets louder and louder for the patient, then.. nothing. From what I recall, it took about 2 minutes to start.
I'm wondering, because I got this type in the hospital.
Sorry if I'm not descriptive, they put me on laughing gas before the injection. And it was months ago.
....And laughing gas gives me a headache. No numbing or anything.
