Would standard lab test show anything for spinal tap complications. leg tingles headache lower back pain started a week after it was performed?

No.: Standard lab tests not likely to show anything. But the worst thing on my list would be infection which might show up as an elevated CRP or wbc. I would see the doc who performed the rudy to have them consider your problem.

See below: Sounds like you have hypogylcorrhachia, or a spinal tap leak, which creates postural headaches, perhaps back and neck pain, and conceivably explains your tingling. If this is indeed the case, a blood patch could fully reverse these problems.
