I have been sick x 2 years, and I Have numbness, weakness, optic neuritis etc... I have had a stressful few weeks and I am late on my IVIG (I get it every 3 weeks, due to this mystery illness), but I just had another bout of optic neuritis followed by new and worse numbness and weakness.. the numb sensations make me want to crawl out of my skin!!! Anyhow, i have muscle atrophy.. its mild, but it's there.. its in my hands, shoulders and butt.. symmetric.. anyhow.. I am the right age for MS (female younger 30's post partum when symptoms started).. had one spot on my brain MRI and questionable on my c spine.. I hate being a mystery!
