I had a Lumbar Puncture 2 months ago to rule out meningitis and it turned out to be negative. I was admitted to the hospital for extreme fatigue, muscle weakness, and headaches. I was diagnosed with migraines and the lumbar puncture was just one of the many tests that they ran. The procedure itself took about 10 to 15 minutes and was very painful, however unlike a lot of the stories on here the doctor didn't miss or have to stick me several times in order to get my spinal fluid. They had me laying down flat on my stomach and used an x-ray to find where where he was going. After the procedure the tech. that helped the doctor told me to move myself to the other bed so that I could be transferred to my room as I was being admitted for further testing. The doctor told me to lay down on my back and be completely still for four hours which I did. I only sat up in my bed after the 4 hours were up however about 3 hours after I did sit up, I was in extreme pain in my back. I never had a headache after the spinal tap apart from the Migraines that they diagnosed me with but it did not result from the spinal tap. It has now been 2 months since this has happened and I have still not been back to work because I cannot bend over at all. My pain is from the puncture site in my lower back and shoots up my spine to up upper back and neck. It also will shoot down my right leg from time to time. Sitting is the absolute worst for me it, I can stand for a little while before it starts to hurt me really bad. A week after I had the spinal tap, I went to a pain clinic and had a MRI done to make sure that my spine is not leaking and its not. I am now in physical therapy twice a week and it does help but only while I am there. My doctors and my PT have never seen anything like this. Has anyone experienced anything like this?
I too have had a lumbar puncture done two days ago for possible aneurysm but thankfully fluids came our clear. I also never had any follow headaches but a very sore back. I asked my consultant when will the pain stop he replied usually a few days after the LP but if it continues after a week consult with my GP for further advise.
Maybe your GP can investigate why the pain is lingering. I'm hoping my back pain doesn't last and pray you recover soon.
