Yes you can have MS and lupus both I have both plus RA and AS , fibromyalgia, neuropathy and other forms of arthritis. I have the white spots on Brain and had to get a 2nd opinion before they found my MS. They say you can live with MS for years before being diagnosed with it or before it will show up on any test. Good luck I hope you find something out.

My first THREE neurologists simply called it peripheral neuropathy!!!!! No MRI. Nothing. My PC humored me and sent me to a FOURTH neurologist, who did an MRI and evoked potential tests and confirmed Multiple Sclerosis, even though my tests do not completely fit an Multiple Sclerosis diagnosis.

2ND OPINION!!! I was tested positive for another auto immune disease called Lupus. My mother and aunt has Lupus and they have those symptoms. My neurologist said that it cant have both. Lupus and MS have some of the same symptoms. I hope you get better soon and relief from your symptoms
