@chaelsonnenfan,
It is unrealistic to expect anyone here to answer with any degree of accuracy. Frankly, based on the info you provide, IMHO it's not knowable other than to say that meningitis is an illness that involves spinal cord, spinal fluid and the brain. As a guess, they must have need to operate on your spine. Back in past, they didn't have laser optics (keyhole) surgery so the scars were more involved and larger.
"Meningitis is inflammation of the protective membranes covering the brain and spinal cord, known collectively as the meninges. The inflammation may be caused by infection with viruses, bacteria, or other microorganisms, and less commonly by certain drugs. Meningitis can be life-threatening because of the inflammation's proximity to the brain and spinal cord; therefore, the condition is classified as a medical emergency"
At some point in the past you might have thought this was important enough to ask the doctor or medical professional?
Sorry to see that you don't have a dotor. Out of curiosity, is that because you have no medical benefits from your past employer or you have made a choice NOT to see a doctor?
