So that straight line on the picture is a needle going into my spine. It hurt, it hurt a lot... If I'm reading the report correctly, the needle was 8.8cm long.
The most fun part was when the Doctor said, "I've got the needle in the right spot, but I just want to test something." and then he pushed the needle in further and my entire leg went into a nerve spasm and felt like it was on fire. The Doctor then said, "Did you feel anything then?" and I cried replied, "Yes."
