Because you are in pain. I have not read your other threads, I do not know your story. For me, the fact that you have pain is enough to create the list of possible theories and explore each of them to the fullest that you can - what is the harm in putting this one on the list? And yeah, exploring or investigating them with a skeptical eye is totally ok, discussing why it doesn't feel right for you is still exploring it. Maybe something else will come up out of those discussions that shines a light on something.
