Lesion location is not a good predictor of effect on one's body unfortunately. If you have a look at the MS health pages there is one on this topic from memory.
there's a good explanation at this site about what the parietal lobes ifluence in our body.

But if I understand the question correctly, I don't think it works quite that way. The lesions cause damage in specific nerve pathways versus damage to the entire parietal lobe - you are not going to feel the symptoms all over your body.
if I've missed the mark here, someone will let me know. ~Laura
Thanks for your reply. I will go through the info.
Thanks for replying. Your answer helped me understand.
I totally agree with Laura......one lesion is not capable of effecting 'all' neuro pathways, so technically because of the sheer number of neuro pathways in the brain, neuro plasticity etc even multiple lesions in any location of the brain, just can't cause sensory issues, parathesia, spasms etc to be experienced 'all over' the body but lesions can potentially cause a specific area of the body, to have an abnormal sensation.

I'm going to slightly disagree, but only slightly. The MRIs show as 2D slices, but the brain, as well as the MS lesions are in reality
3D. Depending on sizes and placements of each lesion, multiple nerves could be impacted.
But true 100% bodywide, that's a far, far reach.
Thank you for your answers.
