I torn lateral meniscus no feeling in my legs towards spasm all over my body. Drs. Suspect ms. What could this be?

Hard to say. Hard to say. As it sounds like your doctors suspect, simply tearing the lateral meniscus of the knee itself does not explain all your symptoms. Ms is characterized by episodes of neurological symptoms and will often be accompanied by specific exam findings and lesions seen on mri. Vision changes are very commonly seen in ms as well. Thank you.
