Ms symptoms. mri white lesions on brain requested lumbar p. could it be anything else than ms. feel like going mad waiting for appointments & answers?

Sounds like you are: really anxious. It really wouldn't be wise to try to guess at your possible diagnoses with so little information. I know it is hard to wait but for an accurate assessment, appropriate testing really is the way to go. Hang in there.

Broad differential: The information obtained from the LP is critical to establish or help rule-out MS. The differential diagnosis for MS is broad and includes tumor, stroke, acute disseminated encephalomyelitis, sarcoidosis, transverse myelitis, and vasculitis.

Yes, other items: Lesions on MRI could be due to smoking, hypertension, migraine, prior head trauma, aging. But if you have symptoms raising concern of potential MS, need also to rule out lupus, HIV, Lyme disease, B-12 deficiency, Sjogren's, syphilis, vasculitis/arteritis, anti-phospholipid antibody syndrome, even copper deficiency, etc.
