My diagnosis has been changed recently from CIS to RRMS. I'm currently waiting for my latest MRI to be reviewed so I can start DMT. My memory seems OK but my walking and grip is affected. I am finding though that if too much is going on around me I become overwhelmed and cannot concentrate and end up becoming really snappy. This kind of thing never used to bother me and I could block out and carry on but over the last few years it's getting worse and worse....too much noise around me feels like a car crash in my head. I've never associated this to MS but could it actually be part of my MS that is causing this feeling/reaction?
