I had a lumbar puncture 2 days ago. That night I had trouble sleeping and took 2 benedryl. I also had a little back pain so I took 1/2 Tramadol tablet. A few hours later I woke up in a pool of sweat and was drenched through. I got out of bed to use the restroom and barely made it to the bathroom before feeling like I was gonna vomit. I tried to make it back to my bed but ended up passing out. My husband found me in the floor by the bed. Is this serious? It has now been about 53 hours since the spinal tap was done. Thanks.
