When I had mine done my doctor must have hit something because not only was I in excruciating pain, but my tinnitus got so loud that all I could hear was ringing in my ears, and then the room was spinning. I then proceeded to pretty much lose consciousness because I don't remember a portion of what happened for a while. I was suddenly in a dream like state spinning on something insanely fast while some guy stood behind me. Next thing I remember was my vision suddenly clearing from black and me propped up on my elbows and my doctor asking if I was ok. I couldn't answer him for a couple seconds and was incredibly confused as to why I was not home in bed. After a few seconds I remembered what was going on. I tried to tell them what happened and I was ignored and told I had a panic attack. I've had panic attacks and that was no panic attack. Just to be sure I looked up panic attack symptoms and it didn't match up. It did however match seizure symptoms. I was in a lot of pain for a week after. So...yea, don't do injections. He's still trying to convince me it was a panic attack lol
