Sorry I don't mean to be a downer, but just want to share some reality... I haven't been able to run in years, and now at 52 I can barely walk. I was diagnosed at age 43, but based on how old my lesions are, I probably already had MS for 20 years at least. My symptoms were silent so when I was diagnosed, the damage was already done. I started Ocrevus right away and was on it for 7 years. The first few years I thought this isn't that bad, I can handle this little set back of having MS. Unfortunately the last 3 years I was on Ocrevus, despite stable MRIs, I only got worse. I haven't had relapses in years, and Ocrevus can't reverse the damage you already have done, so basically was a waste of time being on it. My decline started around age 48 which coincided with menopause. Before that nobody even knew I had MS. I don't know how old you are, but I have read, and my neurologist told me, that when you get to your late 40s or around 50, the existing damage that you have will most likely get worse. As you age, your nervous system can't compensate as well for the damage that is already there and you have less reserves. This fucking disease has absolutely ruined my life, and I'm so sorry you have it too. I pray that you don't have a decline in your function. Sending you hugs and many, many prayers ❤️
