For what it's worth, because we all experience different symptoms and events with this disease, I will give you my 2 cents.
I notice that I twitch a lot in my right hand, but mostly when I am overheated. I asked my neurologist about this during a visit and he said it was attributable to the MS. It is not painful and not really annoying at this point. I have had some other twitches, but again, they are not bothersome. I used to get twitches in my eyelids, but that was before the diagnosis or any thought of MS. Perhaps it was related.
When I moved to Argentina a year ago, I fell down on the sidewalk 5 times within the first 4 months. I blamed it all on the uneven sidewalks, but when I saw the neuro a few weeks ago during a bad relapse that caused me to fly back up here, he said that this being clumbsy is related to a few lesions that he saw that have cropped up recently and showed up with the MRI with contrast -- they were enahncing.
So, while I hate to put everything that happens to my body on the MS, I am thinking that it probably is. It's too bad I was so stubborn because it's likely this relapse started when I moved. It was still summer in March, April and May and it most likely brought it on. I should have found a neurologist immediately and gotten checked so that I could have gotten on the IV steroid treatment, although I would not have liked to have experienced that in Argentina. The standards of medical hygeine are not what we are accustomed to here.
I would say that if you have things that are happening that you can't explain, or that bother you physically, or that you worry about, that it's well worth seeking medical advice.
One thing I don't see people write much about on these boards is the MS Society or the organizations that help patients on the medications that they are taking for MS. I called the MS Society during the big relapse that put me in the hospital and ended in the MS dx and they were very kind and caring and helpful. It doesn't cost anything and they are there for to help. If nothing else, they listen and understand and have referrals if you need one for good doctors in your area.
