[|Human|] I had a lumbar puncture today that came back with normal results after 24 hour a headache that was sudden onset and photosensitive and half hourly vomitting for atleast 5 hours until I got to the hospital and was gven IV analgesics, paracetmol and a lot of morphine. I am now home again and have blood in my stool. Could this be related to the LP?
[|AI|]  Hi, The headache is very likely due to the LP but not the blood in the stool. If you are actually seeing bright red blood in the toilet itself then, it is more likely than not hemorrhoidal bleeding. If the blood is within the stool itself as a formed clot or if the stool is tarry in color then, it is still not related to the LP but does indicate the possibility of an upper GI bleed and if you received IV paracetamol I am wondering if that could've been a factor since that medication can cause GI bleeding. Hope I have answered your query. Let me know if I can assist you further.
