I have MS and also used to deliver training on it (so have some idea from both points of view). MS is different for every person affected by it, and personally I found that just after I had been diagnosed every other person would tell me about someone they know with it and then reel off ways in which they are affected. It's so important to not listen to stories about other people and relate that to yourself, for factual, accurate info, The MS Society are a fantastic resource. No two people are affected in the same way, so you really can't look at someone and say 'that's what it's going to be like'.
I found the fact that MS is so uncertain/unpredictable pretty hard to get my head round for a while. I found that talking with other people also affected by it really helped me, although that's not for everyone.
I was diagnosed at 29 (am now 41), with aggressive RR (Relapsing/Remitting) MS, and I still live a full, active life. I am however a wheelchair user, but this is NOT due to the MS. I had an accident where I ended up in a wheelchair temporarily, but whilst was off my feet for 12 weeks the MS 'got' me. So, to look at me I'm a stereotype - MS and wheelchair user, but in actual fact the MS isn't what put me in the chair, but ultimately it's what's kept me in it.
I had chemo treatment Alemtuzumab (Lemtrada), in 2008, and I was given another MRI scan last year and the results show that my MS has not progressed or relapsed since then. I went from relapsing every month, to nothing for 9 years!
If it does turn out to be MS, there are so many new and hopeful treatments out there.
If you want to PM me, I'll gladly chat with you.
