Desperate for a Diagnosis: Numbness, Pain, and Blurry Vision

I'm losing it, I swear. I'm currently seeking a diagnosis for some physical/neurological issues Ive been having that recently had a massive flare. my best guess is MS or something similar, there's only one or two ms symptoms I don't get. these problems have caused severe pain and have made me unable to work recently not only because of pain, but also because I'm mostly numb. I can't properly feel anything, I can't tell where my feet are half the time, I'm struggling to walk, my vision is blurry and difficult to focus. I've already been to the e.r. and the literal only test they did was a lumbar CT and they ended up giving me muscle relaxers and corticosteroids. They just told me to follow up with a Neuro and discharged me. they discharged me two weeks ago and I still can't walk right. I don't have insurance and can't get into a neurologist, I can't work, the e.r. didn't help me... I just don't know what to do anymore.
