Late to respond, and I haven't read through all of these, so I may be repeating. But here is my story -
My sister found out she had MS when she was 28, with two small children. She thought she had an eye infection that was actually a lesion on her optic nerve. I hear it's common to find out this way. She was put on medications - there are so many options out there and you will have to work with your Neuro to find the one that is right for you. They all have side effects and are expensive, but some affect people in different ways than others, and cost is usually picked up by insurance. My sister meets her deductible in Jan every year. She started with a baseline MRI - funny (ironic, not haha) story, she had an MRI done about a year before the MD diagnosis because another one of our sisters has a vascular disease that affects the blood vessels in her brain. Some of us chose to get an MRI to rule it out in ourselves. This sister was one who got one.
The neuro was able to tell, from the first MRI to the 2nd, about a year apart, that there was no sign of MS lesions at all in the first MRI, so they believe that her MS developed within a short time frame between the ages of 27-28. She is young for such a diagnosis, but she knows she did not have it before age 27 - at least no signs of it.
Her biggest complaints/symptoms in the past 11-12 years has been numbness with the flareups, and the side effects of the medications. She has been on daily injections, pills, IV's, the works. Certain medicines have made the flareups either less intense or farther in-between. I'm sorry that I don't know the names of the medications, but there have been so many advancements and new medications that have come out in the past decade that I'm sure there will be one that works for you.
Lastly, I wanted to let you know that I am a part of a 20 year MS study (about 4-5 years in, currently) through Brigham and Women's Hospital, Harvard Medical School, and the NIH in Washington DC. It's called GEMS if you look it up online, and you and your first degree relatives might qualify if you are interested. It's mostly occasionally answering questionnaires via email and surveys, but I have also given blood and saliva samples (they send everything you need and everything is prepaid - you just go to a local lab that does blood draws and give them the paperwork - they do the rest), I have been flown out to the NIH in Bethesda MD to do a two day MS testing with a MRI (they brought my sister out with me and did one for her as well....and anytime she is in the DC area and wants to do another MRI, they will do it for her for free).
Currently, I am in the middle of a two week period where I am wearing a actiwatch (like a fitbit) that is recording my sleep patterns. They sent me the actiwatch in the mail with instructions on what to do, and in 10 days - this is day three - I will throw it back in the prepaid box with the paperwork and ship it back.
Feel free to PM me if you would like more information. Good luck to you - my sister is about 11 years into her initial diagnosis, and she just spent NYE in Times Square with her teenagers and DH standing for hours waiting for the ball to drop with no problem. She has had her good days and bad days over the years, but all in all, she is doing great and you cannot tell she has MS from the outside at all. Her tests at the NIH were really good, and that was at 9 years in. The advancements in treatment and research have been amazing in recent years - make sure you find a neurologist who is willing to sit with you and take the time to go over all of your options to find the best treatment for you. Good luck and hugs to you
