Medical malpractice is very difficult to prove.
You have to be able to convince a judge or jury that the physician or medical practitioner acted in negligence or outside of the standard of care.
A defense attorney could easily... very easily explain that your symptoms of back pain are a result of the suspected meningitis, an unfortunate side effect of whatever was ailing you.... not the spinal taps.
UNfortunately, people throw the term "malpractice" around quite caviler without understanding what it truly means.
Your best bet is to sit down with a REPUTABLE attorney who handles malpractice and ask them.
