Hi! I m 19 and going through treatment for acute lymphocytic leukemia (starting In November of last year) and have received several lumbar punctures-most of which have gone perfectly fine and have not been painful! The last four though have been really uncomfortable afterwards- the procedure goes fine and I don t feel a thing, but then about 5 minutes after they have me lie on my back, my tailbone (literally the end of my spine- my coccyx) starts to have little spasms that are extremely uncomfortable! They started as just really weird (seriously the weirdest) ticklish/itchy and very sensitive sensations, and usually get better-like go completely away after walking around for about 2 hours! Today I had another LP though, and I think it s the worst pain I ve experienced so far in my life! (It s hard to really think about it cause of the whole chemo brain fog thing going on here) Today I laid down for about 10 minutes after the procedure was over before I knew I had to get up and start walking this weird feeling off, like I ve done the last couple times to make it stop, but the pain was SO much worse!!! My coccyx burned and stung and I lost control of my bladder! I know this is a weird situation, but my doctor and nurses don t really know what s going on and I was just wondering if there s any outsider perspe! Thanks!!
