A blood pressure spike of 230/160 is what led to my MS diagnosis. Just a few months ago it dropped to 68/45. I have been on/off BP meds since I was a teenager (in 40's now)..now it makes sense. Last 6 yrs I have had all these hospitalizations & test because BP like that has to be heart related....wrong. A year and a half ago they finally figured out my erratic BP and chronic insomnia (9 months of sleeping 2-3 hrs a night- no RLS or sleep apnea) was due to MS. My neurologist and family doctor said my symptoms were so atypical that is why it was missed all these years. I was just about to the point where I thought I was a hypochondriac. Had my normal family doctor not been on vacation and I followed up with the partner covering, I probably would never have been diagnosed properly. She took the time to listen and test, not just change a BP medication. Odd thing, she found it because the BP, after the previous week's spike, was 118/80 and I had been dizzy and I described words sliding together while reading- dizzy is usually low BP and headaches are high BP. I've never had a headache when my BP was stroke level, and when it is low I haven't been dizzy. One thing about MS is you can't compare yourself with others and you have to trust when your body is telling you that something is off.
