Done. A half a dozen shots of local anaesthetic in my lower back, a needle into my spine, tap off a few drops of spinal fluid followed by an injection of chemo into the same hole. I then had to lie on my back for a couple of hours.
The local didn’t sting much. The only little discomfort was caused by hitting a nerve when the needle went into my spine. I felt a nerve twinge in my leg and right bottom. No after effects though so not too bad.
