Hi Denna,
The strange thing with MS is that new lesions do not always cause a relapse and that new symptoms do not always mean there are new lesions. The two are independent of each other (most of the time).
It is certainly something to take note of (new symptoms) so that you can report them to your neurologist. If they get worse and/or interfere with being able to do the things you need to do, then consider calling the neurologist about the relapse.
Things like new "buzzing" are sometimes just entertaining (in my experience) although they can be annoying. I hope that you are feeling good otherwise. It's good to see you here.
Welcome Denna. Get used to it
. If you hadn't had all kinds of weird sx in the years before your dx, you were lucky. What I have learned in the last 11 years since dx (the sx were there for at least 25 years before!) is that every day is a new story
. We get used to it.
Happy, feeling good holidays,

If new lesions don't cause a relapse, what does? For years I've been trying to get my neurologists to explain how the location of my lesions in my brain might affect the activity that that part of the brain controls. They don't really know, right? I've got some in the pituitary hypothalamic region and that that is why I think my thyroid is now a multinodular goiter. My occupational therapist told me that lesions near the hearing part of the brain can cause the brain to signal that you're dizzy because the brain cannot interpret the mixed signals. The brain wants you to sit down because something appears to be very wrong. She said I had to re-educate my brain to accept the mixed up signals as normal for me. I don't think there has been enough research into how our lesions affect our sensations, our cognition, and our physical movement.

Thank you for your response. I am still getting used to what to expect since being diagnosed in April 2009. I kind of just take it as it comes but I am not always sure when to be alarmed or if it is just part of life with MS! I am doing well outside of this and I am very thankful! Hope you are well too, have a wonderful holiday season, take care.
