Wow you have a lot going on!! You are not a fraud if what you want is a friendly ear and some kind advice. We can certainly offer you that. Optic Neuritis is frequently associated with MS but not always. The MRI will be able to tell you more so try to be patient. The IV solumedrol is a frequent strategy for both Optic Neuritis and for MS. You will be hooked up to an IV (some have to go to a hospital or health center, some get a home health nurse that will visit) and the infusion will take about an hour. You may get sort of a metallic taste in your mouth. You will get a decent boost of energy and you will probably have trouble falling asleep especially the first night. You will get horrible heartburn so get on something as quick as possible to treat that. Other than that, it is really not that bad. Just keep in contact with your doctor.
Let us know how it goes with the IV solumedrol and the MRI. We are here for any questions you may have. I hope your vision improves real soon.
