Hello, I don’t know if I will be diagnosed with MS or not yet but I have had optic neuritis for weeks. We have to follow up with further testing but I can’t get anything done until I finish 21 days. I’m having horrible side effects from the steroid and I don’t know how I’m going to get through 21 days…. Any suggestions on this? He won’t do a spinal tap until after my course of steroids.
