I do believe I experienced that pain.Interesting story. Although it makes me wonder if your your situation was more about memory then it is about the relation between experience and consciousness.
Presuming you were conscious of the pain at the time, then I would agree you experienced the pain. Forgetting an experience does not mean an experience did not happen.
However, if your body went through the experience by itself, without you being consciously aware of it at the time, then I would have to say you were spared the experience.
The fact that you were screaming, inclines me to think the first is more likely.
My arm was broken as a result of a fall of about 8’. I had a 2 point landing. My hand hit first and must have took a good part of the impact with a concrete floor. My head hit after my arm collapsed. I had a broken wrist, severe concussion, skull fractures, and a blood clot on my feeble brain. The clot almost killed me. I was alone when I fell but was conscious when a coworker found me. He said I was still walking around and acting all right when he took me to the Hospital. I have no memory of the 10 days I spent in ICU. My friends and family all said I was acting normally. I have no memory of that either. Memories like mine are probably hidden someplace and can't be accessed.
